Do those of you in the cold cold north allow your hens to sit in the winter? My silkie/ee is determined to sit on eggs, but we have already had two frosts and it's getting really cold really fast. I am leery of hatching chicks in the late autumn/winter. My concern is not only the cold, but the fact that they tend to stay in the coop more during the winter. I fear the likelihood of the flock going after the chicks goes up being confined. What are your thoughts?
