I need advice on what to do about one of my pullets. She has been setting on about 10 eggs for the past 6 to 8 days and I know that she's going to stay there (she's made it very clear). The weather has been between 10 and 30 degrees lately and I can't leave her in the coop with the others because she's been attacking them to defend her nest. We don't have any other place that's very warm though. She is less than a year old and she's a buff orpington. We want her to be able to hatch the chicks but I fear that it's too cold. Any advice on what to do is appreciated.
