I have 3 broodies. I gave 3, 6 week old chicks just now to a broody who is under one year, and 3, 4 week old chicks to another who is one year old both had never raised chicks, both were very willing to take the babies. my last broody, wanted the 4 week old chicks, I just don't trust her to not peck. She is 3. She is good at sitting on eggs though.
