Hen/pullet puffed up standing on 1 leg - hasn't layed in 1.5 months

[ella2025]

So do we think they are just cold and Orpington stopped laying because of winter? The Brahma hen/pullet that I said is a bit less skinny than Orpington stopped laying a week or two ago. Right now, my best layer is a... Drumroll... Silkie! She has always been super consistent in laying, stopping only for a short broody session that I broke within a few days. But she's a bit puffy too from what I can see. Pretty much all my hens are and I think maybe that could point to them just being cold?
