My barred rock hen went broody for about three weeks before I gave her six fertilized eggs to set on. Two days ago, four cute little chicks were hatched and the remaining eggs were discarded. I live in Pennsylvania, and it is getting cold. I have Mom and chicks in with three other grown hens, and I was taking my chances, since she was the alpha female, and I think she can protect the chicks. I wonder though, that since she has technically been setting for about 6 weeks total, and to keep the chicks warm, she is still sitting a lot, if I should take the chicks and just raise them inside with my heat lamp. ( I raised the other four hens from chicks, so I have all the equipment. ) I am afraid that she is going to get weaker and cold herself, since feathering for the new chicks is about another 4 to 6 weeks away. Should I help out Mama or let nature take its course?
