A few days ago I discovered 18 eggs under a tree. They were laid by wild chickens, but no one seems interested in hatching them. I don't have an incubator, but do have several silkie hens. One of the hens is kind of borderline about sitting on the eggs, but there are too many for her since I found another 9 in her house. Is there a way to force one of the others to help? Is it advisable? Or should I just take their word for it that they aren't going to do it?
