I have 3 week old Bard Rocks and I just added some Buff Orps only 1 week old. They are significantly smaller than the BR. I don't remember the BR being that small at 1 week, but anyways the BO are scared of the BR and not sure if I should separate them. Of course there is a BR that likes to peck at them. I feel so bad that the BO's are all cuddled up in the corner. Whatcha think I should do?
