I noticed this morning while my blk astralorp was in her nest laying her daily egg that one of the other chickens was actually sitting by her and watching. Her neck was stretched out and if she could have she would've been behind the hen. Her and her sister have been squatting a lot. I didn't know that they would actually watch another hen lay! I'm guessing this is normal behavior? Are there any other signs that they are getting ready to lay?
