Two of my favorite hens had gotten broody, and I happened to mention to my vet that it was a shame they would never hatch anything, because I have no rooster. She gave me 4 fertile eggs, and I put 2 under each, and pretty much forgot about it. Yesterday, one of the eggs hatched! I checked the other eggs, and they were not viable. I know someone with week old peeps. If I put one under the broody hen, will she accept it? Can I give the one with the newly hatched chick a week old chick? This is all new to me.
