My Hen has been setting in 4 eggs for a little over 3 weeks. I am proud to say I am a grandma of 1 baby chick! BUT here's my dilemma: the nest is in a coop which is about 4 ft off the ground, and when I went out this evening to check the nest I found mamma with baby down on the ground. How long can she stay off the other 3 eggs without them dying? When I felt them they were cold, and I have no idea how long she's been away from them. I went ahead and put baby and mamma back in the nest. So, now I have a ton of worries and questions about their survival. Please help me.
