Overview
If a chicken's wound is turning yellow or grey, it doesn't always mean something is seriously wrong, but it does usually mean the wound is not healing as expected. Yellow can be a normal part of scabbing or healing tissue in some cases, while grey can suggest dead tissue, dryness, contamination or slower healing. The main thing is to check the wound closely and watch for changes in swelling, smell, discharge or the bird's behaviour.
There can be several possible causes, so it's best not to assume it's just part of healing.
Things To Check
1. Check whether the colour change is only on the surface scab or whether the tissue underneath looks wet, thick, dull or unhealthy.
2. Look for redness, heat, swelling, a bad smell, discharge or any sign the area is getting bigger.
3. Notice whether the chicken is eating, moving and behaving normally, or whether it's quieter, hunched or avoiding use of the area.
4. Check if the wound is being pecked, scratched, rubbed or reopened by other birds or by the chicken itself.
5. Think about whether the bird has been in damp, dirty or dusty conditions that could slow healing.
6. Make sure you can still see healthy pink tissue at the edges rather than only grey, yellow or blackened areas.
7. Check whether the wound is getting smaller over time or staying the same for several days.
Common Causes
The most common reason is normal scab formation mixed with healing tissue, which can sometimes look yellowish as it dries.
A wound can also turn yellow if there is dried discharge, dirt or bedding stuck to the area, especially if the bird has been in a wet or dusty environment.
Grey tissue may happen when the wound surface is drying out too much, or when part of the tissue is no longer healthy and healing has slowed.
Pecking, rubbing, repeated scratching or a wound that keeps reopening can also delay healing and make the area look worse.
Less commonly, infection or deeper tissue damage can cause the wound to change colour and heal poorly.
What To Do
Keep the bird somewhere clean, dry and calm so the wound isn't being dirtied or disturbed.
Check the wound once or twice a day and note whether the colour, size or amount of discharge is changing.
If the wound is dirty, gently clear loose debris using a method you already trust and are confident handling, then keep the area as clean as practical.
Reduce the chance of pecking by separating the bird if needed, and make sure bedding, water and feed areas are kept clean.
If the wound does not look better over a couple of days, or if it starts to smell, swell or ooze, it's sensible to get a vet's advice.
