We have a 21 week old Buff Orpington that was acting very strange this evening. After feeding the chicks some garden treats, one of my chickens got all fluffed up and stood very still. She was acting like she was maybe going to lay an egg (We haven't had an egg yet so not sure what the hen acts like before laying). She did poop a couple times and after 10 minutes or so she was back to scatching around. Anyone have words of wisdom?
