Yes I was wondering, I have had limited experience with hens, this time last year all I had was a cat and 4 naughty horses!The silly girl is likely broody. Do you collect eggs regularly? My silkies had a bad habit of going broody anytime an egg stayed in place longer than a day. Regardless of season.
Eta I've got one girl who desperately tried to hatch a clump of snow last year.
She has spent the last 2 nights in the nest box, tonight she is roosting tho... But yep when she gets in that nestbox she stays there for hours growling if I go near her. I collect eggs throughout the day, usually get about 3 to 6 a day depending on who is laying them, I will make sure to remove eggs from her. But now I am ok with her sitting in the box I am sure it's warmer for her rather than wandering the barn while it's sub zero!!
I guess feathers won't be back till she molts? If she is broody?
