I have two set of "babies" that I need to integrate. The older ones are 14 weeks old, and the younger ones are about 11 weeks old. The younger ones have been in the run, seperated, for about 4 weeks now. When I let them out with the older girls, the younger ones are picked on relentlessly! The older ones are jumping on them, pulling feathers from the backs of their necks, etc. How much is too much of this stuff??? I just don't know where to draw the line or when to intervene. All the younger ones want to do is get back into their space!! But, the older ones just follow! Also, since my older girls just spent their first night in their new coop, should I consider putting the younger ones in there to sleep to speed the process, since it's brand new to ALL of them????? Aaaaaggghhhh!!! I didn't expect it to be this hard since they are all so young!!!!
