I am watching all these posts! I have 16 7 week old pullets and 2 18 month old gals. The babies are in a large segregated brooder...(the sick area normally) and the big girls can see them. Some mornings I wake up, and the big girls are snuggled up next to the wire by the babies....but when the babies are in their "playpen" in the yard, one of the big girls pecked at them. I am very nervous. These posts help. I am hoping to turn them all together in the next 2 weeks....Should I wait longer? The brooder is getting awfully small for 16 big babies. I do let them loose in the henhouse while the big gals are out foraging but still, I worry they don't have enough room.
