I am very new to raising chickens (four days). I have two Buff Orpintons and two Plymouth Rock hens - all about 5 months old. At the same time I got these I also got two Brahma adolescent chicks. The older hens are very aggressive toward the chicks. Today they were huddled in a corner being tag-teamed by the orpingtons. One of the chicks had been pecked so badly that there was a wound about an inch in diameter. I removed both chicks from the pen/coop and treated the wound with neosporin. The chicks are spending the night in a dog crate. Will the hens ever stop bothering the chicks? I feel so helpless. I hope someone has some good advice! THANKS!
