My hen is 18 1/2 weeks old. She’s been squatting for about 2 weeks now and I think today is the day! She’s acting so restless, panting and trying to arrange the nesting box endlessly. Is she okay? She came up and pecked me repeatedly like she needed something and tried to snuggle behind my back in a chair I was sitting in. She keeps kicking around and throwing stuff out of the besting box. Walking around clucking loud and I even heard the egg song. Is she okay??
