Why does my chicken have a crusty scab on a small wound?

Overview
A crusty scab on a small wound is often a normal part of healing in chickens. In many cases it just means the skin is drying and closing over, but it’s still worth checking that the area is clean, not being pecked, and not becoming swollen or messy.
There can be several possible causes, including a simple scratch, pecking from another bird, a bump on housing or equipment, or irritation from dirt and damp around the wound.
Things To Check
1. Check whether the chicken is acting normally, eating, drinking and moving about as usual.
2. Look closely at the wound for redness, swelling, heat, discharge or a bad smell.
3. See whether the scab looks dry and settled, or whether it keeps getting wet, rubbed off or opened again.
4. Check the bird for pecking from flock mates, especially around the wound or any bare skin nearby.
5. Look at the coop, run and perches for sharp edges, rough surfaces or anything the bird may have caught on.
6. Check whether the area is staying clean, or whether mud, bedding or droppings are sticking to it.
7. Watch for any change in the chicken’s behaviour, such as flinching, repeated scratching or isolating itself.
Common Causes
The most common cause is a minor scratch or peck that has started to dry over and form a scab.
Another common reason is repeated irritation, especially if the bird is being pecked by others or the wound is rubbing on something in the environment.
Dirt, damp bedding or droppings can also slow tidy healing and leave the scab looking crusty.
Less commonly, a small wound can become infected, which usually brings more redness, swelling, discharge or discomfort.
What To Do
Keep an eye on the wound over the next day or two and make sure it stays dry and as clean as you can manage.
If needed, gently clear away loose dirt from the area with clean lukewarm water and then leave the scab alone rather than picking at it.
Check the flock for pecking behaviour and separate the bird if it’s being repeatedly targeted or can’t be left alone to heal.
Review the coop and run for anything that could have caused the original injury, then make small changes to reduce the chance of it happening again.
If the scab is staying dry, the bird seems well and the area is not worsening, simple monitoring is often enough.
When To Contact A Vet
Speak to a vet if the wound is getting bigger, the scab keeps coming off, or you notice swelling, pus, heat, a strong smell or clear discomfort. It’s also sensible to get advice if the chicken seems unwell, stops eating, or there’s no improvement after a short period of careful monitoring.
Products That May Help
For small flocks, keeping the coop and surrounding areas clean and easy to monitor can make it simpler to spot new scratches, pecking damage or dirt around healing skin.
