I have a 5 month old cockerel that savaged one of my hens. The underneath of her wings are bare to the muscles. I have her separate in a box where no one can hurt her. She seems ok, she was eating rice and making normal noises (she’s very talkative). I sprayed with chlorohexidine and she’s quiet now. Can a hen recover from something like this? Cockerel is living his last night outside away from the other girls, as I refuse to let anyone else get hurt. Thank you for any and all advice or help.
