I have 3 chickens - 2 have been laying all winter and 1 started molting in November and is now fully feathered but not laying again yet. We've noticed that the non-laying hen has gorgeous bright yellow legs. The 2 laying hens used to have similar legs but their legs have turned a very pale almost beige color over the winter. Are they not getting enough protein? They have free choice high quality layer feed and lots of fresh veggies every day plus a bit of scratch and oats in the morning. On cold days, they don't seem to want much layer feed. I'm starting to worry about them. Is it just a winter thing? Don't know if it matters but they are all silver lace wyandottes and not quite a year old.
