I need help!!! I have had 3 sexlinks, 2 black jerseys, and 1 delaware prolapse when laying. The other chickens keep pecking at the blood till they kill the hen. I have been able to save 2 by catching them at the time of the prolapse. Please help. I am still feeding starter, laying pellets, scratch, oyster shell. The hens are about 10 months old and have been laying even in the cold weather. I am so upset. I hate laying time because of the prolapse.
