Crowing
She doesn't even need the sweater you have her in, honestly. Chickens are basically wearing a down coat 24/7 that keeps them nice and toasty warm. No supplemental heat is necessary. She will be the chicks' heat source. If you feel like the other girls are going to bother her a bunch and you have the space in the coop, you can try moving her to a pet carrier or dog crate. That way nobody can bother her, but she's still a part of the flock. Make sure she gets off the nest at least once a day.
