The chances are real good! As long as she sets, and she's in a nice place where she won't be bothered much, I bet they do hatch, as long as they're fertile.
She is in a safe spot in the coop. I moved them from outside to inside because its safer if she is inside and she was fine with me moving them....she only gets off them to go outside for a minute than goes back and sits on them and I'm pretty sure they are fertile because she
is with a tom ...So we shall see what happens
