Hey all! I was given 4 baby chicks that are about 4 weeks old. I have a silkie hen that has been broody about a week. We moved her to a secluded area away from the flock to sit. We would like to give the babies to this mama to raise but are they too old? I've googled around and found good things about giving broody hens 1-2 day old chicks but haven't had success finding anything on older chicks. Thanks!
