I got 2 new, 5 week old chicks. And have had inroducing new birds into a flock problems before (to the stage where they still don't live together) and won't to do it right this time! When and how can I introduce the 2 chicks to live with my silkie and RIR bantam hens? I have had the chicks in a fenced cage while the older birds roam, allowing the birds to see but not toutch the chicks. I have another 3 hens (Big bullies to the RIR and silkie) too. They also have seen but not toutched the babies. I NEED the two newbies to live with the other 2 bantams in harmony as quick as possible. Help? Oh and one of the two chicks seems to be a boy, and the other is a girl. Boy is rather mean to girl, girl isn't scared of boy but boy does chase her and peck her around too. Do you know why?
