I have a flock of approx 16 week old hens (25) and 1 roo. Adding to them, I have 9 newbies - that have been in a brooder in the big girl coop since they were two days old. They are about 8 weeks old now. The nine newbies have at LEAST 1 roo, possibly a total of three, I cant tell on the Amerucanas yet. The brooder they are in is now just chicken wire separating the big guys from the little guys. I tried to let one of the more curious little ones play in the yard with the big girls and roo today, and they were having none of it, pecking, chasing, terrorizing that poor Amerucana baby, till she/he jumped in my lap and eventually fell asleep of sheer exhaustion lol How do I integrate the smaller ones? The coop is plenty large enough, and the run is 2000 SQ ft. I thought by letting them on "neutral ground" like the yard, not the run, they might not be so aggressive, but me thinks I was wrong. Are the little ones big enough to introduce yet?
