I have never had a mother hen to hatch out her own eggs before. We always bought day old chicks. My problem is she has hatched out 2 healthy chicks and ejected the renaming eggs from the nest. I put them back after a couple hours when she didn't put them back under her. Now she has moved to another spot in her box with her babies and left the other eggs. I kept an eye on her but she hasn't come back to them all day and they were cold. I candled them and 3 are very full the light only goes threw a very small part at the bottom of the egg. I brought them in the house and put a red heat lamp on them. Will this work? Did I do wrong and should return them to mamma and how she comes back to them?
