I have have 10 chicks I got about 6 months ago so they’re not full sized but one of them is a duccle and she’s about the size of a fist and two two year old silkies who have lost some weight recently and I’m worried about them freezing. I live in Georgia so the chicks are used to warm weather but it’s down in the 30s tonight. I have a jersey giant and some Orpingtons in there that are bigger than the silkies and pretty fat so I’m wondering if they’ll be warm enough with them
