I have had backyard chickens for 13 years. After 12, I took a break for a few years and have been back for a year. I have heard that you can put chicks under a broody hen and she will raise them. My hens have always hatched their own, but I am ordering chicks from a hatchery cause I couldn't find the breeds I wanted around here. One hen hatched chicks about 5 weeks ago and still goes in the nest box with some of them at night. Can I give her the new ones at night and have her accept them?
