I have a tried and true broody who I placed 4 chicks under on 3/27/12. She always accepts them beautifully. I have another broody, who's been broody for about 30 days,(4 years old & never been a mom) so yesterday I decided to get 2 chicks to place under her. At dusk, I put them under her, and I noticed she didn't "talk" to them like my other broody always does, and she would peck them every time they poked their heads out from under her. I left them under her over-night, but this morning, when I went down to see them, they were still under her. I took one out to let it get a drink, and she attacked it. When she stood to attack that one, the one left under her was exposed and she attacked it. I really think she would have killed them. The distress calls from the little chicks sent my broody with the 4 chicks running down to the coop (she was free ranging with her chicks). I know Millie would adopt them in a second, but my question for y'all is, have you ever heard of a mother hen adopting chicks of different ages. Her 4 chicks are about 3 weeks old, and the 2 new chicks are 4 days old today. I put the 2 chicks on the ground in front of Millie and she tried her best to have them follow her to where she had left her older chicks in a bush. If I placed the 2 new chicks under her tonight, and they began to think of her as mom, do you think the different aged chicks could blend? Could it work?
