One of my SFs is acting strange. She's not quite 7 months old and she's been laying about a month. She is out and about with the other chickens during the day but an hour or two before roost time she heads to her favorite nestbox and stays there. She growls at anyone that gets close to the box. My poor silkies! They are used to roosting on top of that particular box and I saw that they were very hesitant to jump up on it tonight because of her growls. In the morning the SF will be out again. She hasn't pooped in the box overnight, so far. She just tucks her head and goes to sleep. Being broody challenged I'm not sure about all this strange behavior from the young girls. Is she trying to go broody or just confused about the whole laying an egg process?
