For the past few days, one of my hens has been staying in the coop pretty much every time I check. I got married this weekend so I have been preoccupied with that but I finally went to check on her and she was just laying on top of about 5 eggs. She is also clucking a little differently. I made her get out of the coop today and she seems fine, but sounds different. Is this something typical? She's just a year old Australorp. Should I be concerned.
