I just got 4 chicks this past weekend. I would estimate at this point 3 of them are about 5 days old and the 4th is 7 or 8 days old. The oldest, a Barred Rock is a big bully and has been picking at the other's toenails. She just pecked off a toenail on my Ameraucana, who is the smallest. She was bleeding so I used an antibacterial pad and some neosporin on her toe. I then put a screen in the brooder to separate the Barred Rock so she can't hurt the others. I also hung a little bell on her side so she would have something to play with and peck at. Am I doing the right thing? At what point should I try to let them be together again? Thank you!!
