i have a bo hen. when i went to check on the chickens , she was tucked into the nestbox. i figured she was just laying, weel i went out there about 2 hours later and she was still sitting there, when i came towards her, she growled at me and tried to peck me. ive been in the coop working and all of the sudden one will hop into the box, sit there for about a minute and then get off when i look there will be a nd egg. in there, but ts never taken two hours before. is she broody?
