Tonight, (8:30pm) we were watching the chickens and noticed one of our silkies in the run, looking strange. She was just standing their, in a weird position. She looked like she was constipated and trying to poop. After a few minutes, and egg plops out. She immediately, turned around, pecked it open and began eating it. She didn't get much though, as another hen grabbed it and finished it off. 1. I thought chickens don't lay eggs at night. It happened about 30 minutes b4 sunset. 2. Why would she have done this? I've NEVER seen an egg in the run. 3. Do you think she is making this a habit without me knowing? The way she immediately pecked the egg open made it seem like she's done this before.
