One of our hens went broody, so we let her have 2 eggs just to see what happened. She only started laying about 2 weeks prior. Neither egg was hers, but I knew that didn't matter. We weren't even sure if the eggs were fertile because all of our chickens are under 1 year. One egg either fell out of the nest box, or got kicked out on day 10. Sure enough there was a chick inside. I tried to candle both eggs & couldn't see much. They are on ff food, and I think the shells are so thick. So now we are day 23, and no sign of hatching. She is still sitting on the egg. I'm just wondering how long we let her sit on it, or will she just get off on her own?
