I noticed yesterday my silky who is sitting on 3 eggs got off for a while and was only partly covering the eggs. I was thinking it is probably due to the heat. She was still on them but not tightly and I could see the eggs a little. Later she had them all back under her. My other silky stayed right on hers as far as I know. Is this normal behavior in hot weather? I don't think she actually got totally off them to where they got too cool, i just think she knew they were warm enough. What do you think?
