Im not to sure, but heres some things i found on the internet that may be of help.
1.
The best treatment is applying tiny "hobbles" to the
chick's legs to gently keep its
legs up under them which allows time for the tendons to heal. We recommend Vet Wrap to form hobbles. Vet Wrap will not stick to the
chick's down or
legs but does adhere to itself.
2.
If you find a bleeding chicken in your coop, or if you suspect a chicken’s skin has been cut or torn, it’s important to treat the bird quickly. Chicken skin is thin and tears easily, and bleeding wounds are very attractive to other chickens. Whether the chicken caught on something or was attacked by a predator, skin injuries need immediate attention.
3. For shallow wounds, wash the area with hot water and soap and gently pat dry, or clean the wound with hydrogen peroxide.
If the wound continues to bleed, use styptic powder or pressure to stop it.
4. If the chicken can’t reach the area with its beak and the weather is warm, apply a wound dressing to prevent flies from laying eggs on the wound.
