We got eight chickens, (two roosters, five hens) separately. First we got two 3-year-old hens, which pick on the weak chicken. Then we got the other pair of chickens. One of the chickens in that pair was killed and eaten by an eagle. So the other half of the pair is the weak chicken. After that we got five more chickens. In that group, there were three hens and two roosters. The roosters became a bigger pain for the weak chicken. About a month ago, there was blood on her wings, we put some ointment and a small bandage on the wound. Currently we are nursing her back to full health in the house. But the weak chicken IS older than the roosters and the three new hens.
