Hen Health

Chickens are usually healthy and good husbandry will prevent many problems. Our hens are vaccinated against many serious illnesses, however from time to time  you may be faced with a sick hen.  I am an experienced chicken keeper and have written this guide to symptoms, treatments and prevention of chicken illnesses to help when you have a poorly chicken. If you are still not sure what is wrong with your hen or she is very ill, please consult a vet who specialises in poultry.  As I have provided this health care tool free of charge, I would be grateful if you could support our business by buying your poultry health care products from us either from our ONLINE SHOP or from our premises.

Chicken Problems and Their Treatments

Symptoms: Pale comb and wattles, often caused by parasites
Treatment: Tonic in water, apply Diatom powder to the hen, clean the coop with Poultry Shield.  Nutri-drops can help to revive poorly hens.

Symptoms: Hen sat on nest box, feathers fluffed out, aggressive behaviour
Treatment: All hens can go broody although some breeds are more likely to. If you want her to produce chicks, let her sit on fertilised eggs. If you don't, remove her from the nest as often as possible until she gives up. It may be advisable to wear gloves! Block the nest box(es) off at night.

Symptoms: Feathers missing, wounds, weight loss, reluctance to leave coop, usually soon after getting hens home or adding new hens to a flock
Treatment: Remove from flock if there are any open wounds, Gentian violet to treat wounds, anti-pecking spray, ensure they get food - some bullied hens will give up trying to eat and simply waste away!  Nutri-drops can help to revive poorly hens.

Symptoms: Lameness, swellings on feet, infection occuring after injury
Treatment: Antibiotic from vet

Symptoms: diarrhoea often with blood or mucus, most commonly found in chicks but not exclusively, can result in death or leave permanent damage to the gut
Coxoid in drinking water as soon as possible, followed by a multi-vitamin tonic. Use  Bi-oo-cyst to kill oocysts in coop/brooder and on drinkers, feeders etc. Herb 'n' Thrive can be used as an organic alternative.
Prevention: Vaccination, chick crumb containing a coccidiostat, good hygiene

Symptoms: Hen looks unsteady on her feet
Treatment: Provide fresh clean water, if not drinking use dropper to drip water into her tongue. Don't force water down her throat as she may drown. Nutri-drops can help to revive poorly hens. This may be a symptom of another condition - look for other symptoms.

Symptoms: Runny droppings, dirty feathers around bottom
Treatment: Ensure plenty of clean drinking water is available. Feed only layers pellets or mash, with a little corn if it's winter, until the problem improves. Do not give greens or kitchen scraps.  Nutri-drops can help to revive poorly hens. A Tonic will help if the problem has been long lasting. If you haven't wormed the flock recently, treat with Wormer.

Diet - see  Keeping Chickens: Beginner's Guide

Egg Bound
Symptoms: Hen looks like she is straining with her bottom close to the ground
Treatment: Difficult to treat, oil (vegetable/baby) around the vent may help, if the egg is broken there is severe risk of infection so please see a vet. Can lead to Prolapse.

Egg Peritonitis
Symptoms: Swollen abdomen, loss of weight, laying soft shelled or no eggs, generally looks unwell, if severe can cause respiratory distress
Treatment: Antibiotics if diagnosed early

Feather Pecking
Symptoms: Feathers missing, bloody wound if severe, can occur when new hens are introduced to a flock or if hens are over-crowded, bored hens can even peck their own feathers out!

Heart Attacks
Symptoms: Sudden death, usually in older or overweight chickens, often as a result of stress.

Impacted Crop
Symptoms: Hard lump in the crop, watery droppings, fluid from mouth
Treatment: Drip oil (olive, vegetable) onto the tongue, don't force liquids down her throat or she may drown. Once in the crop and try to massage the lump so it breaks up and can be passed through the digestive system. If this does not work, see your vet.  Nutri-drops can help to revive poorly hens.
Prevention: Use wood shavings instead of straw/hay for bedding and do not pick long grass for them to eat.
