The Sagitta's are doing really well still. They layed all winter long again. However, this winter, they decided they will not step out into that cold white stuff. The pop door is opened every morning, but they prefer spending the entire day in their coop - but they seem to be coping well. I never noticed a molt - some of them are starting to look a little worn around the edges and there are some feathers laying around the coop and run, but not many.
I lost one of my black hens, and another black seems to be on permanent molt - bare back for 3 months and now her tail feathers are falling out and her butt is getting bare. I have dusted her in case of mites, and I see some feathers start growing and then they disappear before fully growing out. Not sure what is going on, maybe she is being picked on. Maybe if it warms up a bit this spring, I will separate her from the rest and see if she will grow feathers back.
