One of my little cochin frizzle girls doesn't seem to have any undercoat at all. I'm kind of worried about her because the weather is really starting to get cold here (teens at night). My coop (acutally an old workshop) I think is insulated but not heated and is quite large so really the insulation doesn't do much good. It is not heated, nor will it be. She spends a lot of time outside by her own choice and shivers when she is out there. Should I make her a little sweater? She has to be about the worst example of a frizzle. Her wing feathers only have main part so it looks and feels like she has little wires sticking out of her skin. She is a sweet little girl and just started laying these gigantic eggs for her tiny size.
