How To Care For A Chicken That Was Attacked. It sounds like this particular dog was not after food but just chasing and playing. We took her to an avian vet.
I almost put the chicken down but it didnt seem to be suffering and I examined it and put it in the coop. Separation from the flock keeps it protected from being bullied or pecked by other flock members and protects the rest of the flock from what may be a contagious. A fox grabbed two of my birds this morning and I caught it taking a third.
If the wound continues to bleed use styptic powder or pressure to stop it.
She is the smallest hen and clearly the weakest but keeps trying to attack. The other chickens will view her as a threat due to her condition and cause stress and attack her. For shallow wounds wash the area with hot water and soap and gently pat dry or clean the wound with hydrogen peroxide. Whether the chicken caught on something or was attacked by a predator skin injuries need immediate attention.
