A Guide to Sick Chicken Symptoms

It's Good to Know Chicken Disease Symptoms and Treatments


With so much talk about chicken illnesses this year, it’s good to know what a sick chicken looks like, so we can try to help our feathered pets feel better quickly. We are all uncertain at times, but there are certain criteria you can use to assess if your bird has sick chicken symptoms. First, let’s explore what a healthy chicken looks and acts like.

How Does the Chicken Look and Act?

A healthy chicken is a busy chicken. It is aware of what the other chickens are doing. The healthy chicken is pecking the ground, scratching the dirt, and chasing others away from a tasty morsel. When you first open the coop in the morning, the chickens should eagerly exit the building, raring to start a new day. They should be happy to see food added to the bowls or feeders and start eating. Any chickens who stay on the roost, or worse, are hiding in a dark corner should be immediately and gently checked over.

When you look at a healthy chicken it looks – healthy!  Feathers are glossy and in place, the comb and wattles are waxy looking and full of color, and the eyes are bright and clear.


Healthy Chickens are Communicating

Chickens talk to each other during the day and some chickens talk a lot! When you spend time with your chickens you will start to recognize certain sounds that are made repeatedly. While my chickens are free ranging, I am often doing cleaning chores around the barnyard. But, sometimes I hear a certain sound coming from my chickens and I just know it is an alarm of some sort. Whether they saw a predator, noticed a hawk in the sky, or were injured by another flock member, the sound is unmistakably alarming. It differs greatly from the regular clucking and squawking that they make. Another alarming sound is any respiratory sound. Coughing, heavy breathing sounds and raspy sounds are signs of serious illness and should be evaluated quickly. With the current wave of avian influenza sweeping the country, it would be good to familiarize yourself with avian influenza symptoms. Always isolate the bird with sick chicken symptoms and reduce the chances of any contagious disease spreading through the flock.

Healthy Chickens have Healthy Droppings

Some may feel this goes a bit too far but notice the chicken’s droppings. There are two basic types of droppings that are excreted daily. One type is often seen first thing in the morning. It is firmer and capped with white urine salts.  Less frequently, the chicken will expel a runnier brown or green, fecal dropping. While both of these droppings will have a slight odor, you should note if the odor is extremely bad or if the appearance is really out of the normal range for your flock. Keep in mind that certain vegetables, such as beet greens may turn the droppings a different color temporarily, without the chicken appearing ill.


Healthy Chickens Have Healthy Appetites

Chickens who are unwell do not eat much. Sometimes they stop eating completely. This is another reason it is good to observe your flock when you are feeding. If a chicken does not come for food, stays off to itself, and is not pecking at the ground for insects or morsels, something could definitely be wrong. What follows next is weight loss, another sign of illness. Young chickens are continually growing and maturing. A young chicken who does not eat enough will not gain weight like the others in the flock. The young birds continue to fill out in size for the first 6 months. Even after egg laying begins, some growth and weight gain can still be occurring. Older hens and roosters should be able to maintain their weight.  The older hen that begins to look scrawny and small, may be suffering from an undetected illness. Some of my chickens prefer to eat from the feeder and some prefer to free range while I am supervising.  Knowing what is normal for them is also a good indication of how they are doing health wise.

Healthy Young Hens are Laying Eggs

Many factors can influence egg laying, including age, molt, weather, stressful environment, and placement of nesting boxes. If you reliably get an egg a day from a good laying hen, and then she stops laying, you may wonder why have my chickens stopped laying? The quality of the eggshell can also be a sign of problems. Thin, weak shells can be caused by inadequate nutrition or inadequate mineral absorption. Knowing what to feed chickens will help you avoid any illnesses due to inadequate nutrition.

Chicken diseases and illness can be caused by a number of things. Viruses, bacteria, molds, fungus, and parasites are the infectious type of illness. Often, if one of these occur, more than one bird will be affected. Some sick chicken symptoms are mild, leading to a day or two of not feeling up to par and exhibiting a low appetite. Other diseases, such as avian influenza can and will wipe out the flock in a matter of days. My recommendation is to not panic when sick chicken symptoms are observed. Assess the bird’s overall health, using the sick chicken symptoms listed here. First, isolate the sick chicken, to help prevent the spread of any possible contagious illness.

Guide to Sick Chickens

Sick Chicken Symptoms

  • Is the bird active or listless?
  • Is the bird grooming or is it unkempt with ruffled feathers?
  • Is the bird interested in eating?
  • Is the bird coughing or expelling fluid?
  • Is the bird able to stand on its own?
  • Is the hen still laying eggs?
  • Is the bird excreting normal or abnormal droppings?

Preventing Illness

As is the case with all types of animals, prevention and a healthy life will go a long way to preventing serious illness. Feeding an appropriate healthy diet, supplementing with herbs, and treating the chickens with probiotic-rich foods will help them ward off many minor illnesses. Fermented feed, apple cider vinegar (2 tablespoons in a gallon of water) and garlic powder added to the feed (sprinkled on top) will all help build a strong immune system in your flock. Clean and sanitary conditions are also important. Removing droppings that attract flies, keeping the coop dry and well ventilated and replacing soiled wet bedding immediately will all help the birds stay healthy.

  • My hen doesn’t want to stand. Is eating and drinking. Can see anything wrong with her legs.What herbs do I give her.

  • Fluffy – My 7 month old silkie had very VERY smelly yellow/green poop, she wasn’t eating and sat away from my other two girls in the pouring rain so I brought her in. The other two hens are broody at the moment (separate issue I’m battling) who are a year old and fluffy has been sitting with them copying. All three have stopped laying and only ate once a day. at first I thought maybe fluffy was egg bound but after warm baths and feeling about I can’t feel any egg in there, so I wondered, has she starved herself? So I’ve been syringing 5ml of egg yoke and water every hour to slowly build her up. She’s eaten about six meal worms today which is more than she’s eaten the last three days and she does look slightly better but she’s not moving around. Her poop isn’t like toxic waist anymore, it’s normal again so I’m hoping she’s on the mend. Are there any ideas what this could be or anything more I can do? She’s such a friendly girl, I think we’ll all struggle if she passes away

  • BTW some chickens will continue to appear to be eating outside as they may keepp head down and peck at grounds. .. this is so that it doesn’t flag them as easy prey being sick or weak for predators. This can be very bad with a sand pile near by our just dirty around. Found this out from a vet when I took a chicken in. She was sick and her croup was packed with sand resulting from this. He told me many similar experiences from chickens to emus.

  • My chickens comb is turning purple she won’t stand she won’t eat or drink by yourself it’s been 3 days kind of worried about her can you give me any signs of what it could be
