We introduced 4 day-old baby chicks to our 3-weeks-broody hen last night without a hitch. They just crawled right under her and she didn't peck them or anything. This morning I went out there and the silkie was huddled outside of the nest on the far side of the brooder like she had been rejected- then I heard the desperate cries of a chick being pecked. I took these 2 out and put them under a warming lamp. I'm worried about the other 2 chicks. Will they be ok? As they wake-up & start moving is she freaking out and deciding that they are invaders? Should I just bring them in now to be raised with the other chicks?
