Again they're probably picking on each other because they're crammed into too small of a space.No I don't. I only did this because 4 of the 3.5 week olds were pecking at the 1.5 week olds and I was trying to provide a window so they could get use to each other while providing a separation.
They’re also a lot younger and smaller/weaker though which can cause picking even with tons of room. Although I do think more room would help in this case, even if it’s just for them to be able to get away easier, but still.Again they're probably picking on each other because they're crammed into too small of a space.
The sooner you get everybody into a bigger area the better.
