Wait until she weans them.Here goes. . . . after raising two batches of hatchery chicks, I now think that the only way to raise healthy chicks is via a broody momma. The six chicks currently being raised by my Ayam Cemani seem to be much happier and well adjusted.
Yes, I just said that chickens are can be well adjusted.
I'd much rather hatch or purchase chicks and integrate early than watch the chicks go thru weaning from a broody.
