I have a broody hen. This is my first time letting her hatch her eggs. She has been sitting in her own brooding box with food, water and straw at her side. She is seven days in and this morning while I was feeding her, I noticed her eggs weren't under her. I was really confused as no animal could get in as there is a wire mesh over her box. I began fratically looking around for the eggs and found them COLD at the bottom of the box!!! I am worried that they may not hatch now. My questions are: how long can hatching eggs survive cold? Will mine survive? What will I do if they won't? Why did she bury her eggs if she has everything she needs right by her?
