My girls are about 20 weeks and one of my cochins is being strange. We figure she is about to lay but none of the others are doing anything like she is. She is constantly laying around in the yard and in the coop like she is nesting and she drops her wings low. She seems to be walking a little funny and sometimes will drop her tail before she plops down. While she is laying there she continues to peck at grass, so she is eating. She has a little poop on her butt feathers but isn't pasted up and her vent looks fine so she seems to be pooping fine. When I pick her up she will sit in my lap which isn't too unusual, they are used to that, but she seems to really enjoy having her rump pet and lifts her tail high when touched, so I figure mating behavior? Does all this seem like normal first egg behavior or should I be concerned about anything weird?
