I have a hen that is sitting on a nest which she built on top of a tool cabiet in a garage. I want to let her hatch them out, but i'm worried about when the chicks are born. The top of the chest is about four feet off the ground. Can day old chicks survive the fall? I don't want to move her and the eggs because she is so tempermental. I only have two options, either let her hatch them out or remove the eggs, and throw them away. What should I do?
