So, I have this Silkie hen in a flock of mixed hens and a couple of roosters. She stayed in the nesting box today with a couple of fake eggs under her. I removed the fake eggs and put 6 eggs underneath her (2 of them were retrieved from the fridge after a day or so). My questions are: 1. Do you think the 2 eggs from the fridge will hatch? 2. Since I don't want to move her to a special pen to raise the chicks, will it hurt for the chicks to eat the flock raiser feed and treats (sprouts, seeds) that I give the rest of the flock or do they need chick starter?
