So I went outside to take care of my chickens yesterday and let my broody hen off the nest. Once I got her off, I noticed one of her eggs was broken and empty. Looks like she cracked it open and ate the insides. I just candled the other day and they were all developing. She has food and water in her hutch, but she won't get off the nest on her own to eat or drink. I pull her off every other day so she can get out and exersize. How can I prevent her from doing this again. We are on day 11.
