Problems with chicken keeping

Submitted by Neil Armitage on Mon, 08/22/2016 - 16:13
  • This section of the site is about the everyday problems that chicken keepers face with stubborn  or sick poultry .

The problems faced by chicken keepers fall into seven categories. Scroll down until you reach the section you are looking for.

  • Health and disease
  • Predators
  • Parasites
  • Injuries
  • Vermin
  • Bad behaviour
  • Loss

 

Do not feel overwhelmed by the length of this article and the unending list of problems. It may be you never have to deal with any of these subjects. It pays to be vigilant and prepared.

Below is an overview of the pest, diseases and afflictions both common and rare found in poultry. Some conditions affect more than one part of the body. These have been placed in the section where the symptoms first become apparent.

Health problems

Respiratory problems and diseases.

Birds in general and Poultry in particular have weak respiratory systems and can be easily overcome by their ailments.

Follow the links below to details pages about the conditions as well as treatments and preventative measures.

<Bird Flu> seems to strike fear into the minds of chicken keepers the world over. Avian Influenza is an infectious virus that affects many species of birds, including domesticated fowl. There have been  outbreaks around the World including here in the UK. There is a compulsory slaughter policy on all infected flocks including within a zone. It is spread mostly by wild birds and human movement.

<Mycoplasma> This is a common condition, birds can get ill or just become carriers. There are several types that affect poultry but Mycoplasma Gallisepticum (M.G) is the most common. There are several strains and some show different symptoms.

<Infectious bronchitis> or I.B is the most contagious poultry disease. It has similar symptoms to mycoplasma. The main difference is the number of birds it affects. Mycoplasma tends to affect a few birds in the flock but IB spreads within a few days to the whole flock.

<Aspergillosis> sometimes called brooder pneumonia because of the warm and often damp conditions in the brooding area. It is an infectious fungal disease and is difficult to treat with high death rates. The birds inhale the spores which begin to grow. Birds will be gasping for breath and those that live may never recover .

<fowl pox> Pox is widespread and in a similar vein to the human variety it comes in two forms. It is a common disease in backyard chickens that have not been vaccinated. Although very young or weak birds may be lost most survive. The lesions initially looks like a whitish blister and appear on the comb, wattles and other skin areas. This may be the only symtoms the bird shows. In rare cases lesions can be found on the body, legs and even sometimes the softer parts of the beak. The blisters develop into a dark scab and take about three weeks to heal and drop off.

Digestive 

 

see also < the digestive system of the chickens>

<Coccidiosis> An nasty little bug that is endemic in poultry. It can cause unthrifty birds at best and death is quite high numbers if left untreated.

<Diarrhoea> Has many causes from heat exhaustion to parasites or pathogens

<Pendulous crop> Common in older birds and ex battery hens that have had commercial diets only

<sour crop> Infections or fermentation in the crop

<impacted crop> a solid crop filled with long grasses or fiberous vegetable matter. Usually caused by insufficient grit in the diet but has other triggers.

Reproductive 

 

see also the <reproductive system of a chicken>

<Egg Peritonitis> The peritoneum (the lining of the abdomen) becomes inflamed due to an infection from bacteria. Peritonitis can occur after prolapse or when yolk goes into the abdominal cavity, instead of going down the oviduct and out in the normal way

<Prolapse> When the lower part of a hen’s oviduct turns inside out and is left hanging outside of her vent. This condition is most common in young hens that have started laying too soon but can be inherited in some pure breeds.

Suprelorin Implant For Chickens - The suprelorin implant was originally designed to induce temporary infertility in male dogs but strangely also stops chickens laying for anything up to six months. With my two implant girls it was a three month and two month respite from egg laying demands. It is therefore ideal for prolapses or

<Egg Bound> Sometimes poultry can become egg bound when a large egg ‘gets stuck’ in the oviduct. The bird will usually keep visiting the nest box without being able to lay the egg and will keep straining. If the abdomen of the bird is examined, the egg can often be felt.

<Infertility> Has a surprising number of causes

<Tumours> Surprisingly common in chickens despite their short lifespan and most common in the reproductive system.

<mushy chick disease> or yolk sac infection.

Malformations and skeletal problems

 

<Angel wing>

<lameness>

<Mycoplasma Synovia bacteria> this myco is here because it seems to infect the bone marrow.

<bent toes>

<slipped tendons>

<malformed breastbones> only really a problem if you breed or show birds. Either genetic or by birds perching when they are two young.

External – Dealing with the outside and extremities of your bird.

 

<bumblefoot or pododermatitis> infection or inflammation of the foot. It is usually caused by a bacteria called Staphylococcus aureus. There are two causes of Bumblefoot. The first is a wound of the foot that allows the bacteria to gain entry. The other is the feet on moist bedding or muddy ground for extended periods.

<fly strike>flies can be a real problem in summer.

<Dealing with spurs> As the males age they can get long spurs. Mostly they do no harm but sometimes need taking care off.

<frostbite or frozen comb> Only a problem if you live in an area that experiances sub zero temperatures. Easy to prevent and deal with.

<Moulting> Chickens get through a lot of feathers. They go through three partial and 11 complete moults before the mature. There after it is generally one a year although it may not be a complete loss of feathers. Some birds do end up looking oven ready almost overnight.

<Broken beaks or nails> Broken nails are not common but rarely  a problem. Ex batts have had their beaks trimmed and broken beaks do happen occasionally.

<Broken toes> One of my flocks gets in with some horses and get their feet trodden on. This results in broken toes but chcikens seem relatively immune to foot injuries

<wounds> Dealing with everything from scratches to the aftermath of fox attacks.

<feathers or the lack thereof> Feather loss has several causes. Some are harmless and some need immidiate attention.

<we need to talk about bottoms>

<your chickens are fat> Overweight hens are rare. Free range is best.

Nervous system 

 

mercifully a relatively short list. Torticollis or twisted neck a symptom of other conditions. Other diseases may show nervous symptoms.

<Marek’s>

<toxoplasmosis>

<Botulism>

<blindness>

Cardiovascular

 

problems with the <heart and circulatory system>. The most common is heart failure which can be acute as in a heart attack or gradual with age. The end result is the same.

<Avian Leukosis> - A thankfully rare virus causing tumours in chicken flocks. Avian leukosis belongs to the retroviruses.

Predators

Where you live effects how you deal with predators. Here is the United Kingdom we are lucky with the predators I have to contend with.

Predators can aerial as well as ground based. Sparrow hawks will take chicks up to 12 weeks old as well as bantams. Kites and eagles will  take full grown chickens.

I have separated foxes into urban and countryside as they are quite different beasts.

Bad behaviour

 

<aggressive roosters> Apart from broody hens , bad tempered hens are a rarity but not unknown. I have one called nipper but that is about the extent of her aggressive tendencies. Cockerels on the other hand are a different story. There are some treatments for the grumpier amongst them.

<Perching problems> Common with Ex battery hens or birds that have not been raised properly. Birds should perch both to rest during the day and to sleep at night. Issues with perching cause mucky bottoms and other problems.

<sleeping in nest boxes> Again common with ex batts. This is unwelcome just because of the mess it makes.

Hens laying on the floor or outside on the range. This is about the most comprehensive article I have seen on <not laying in the nest>.
