I'm not worried about our hens being too cold this winter, but I AM worried about freezing combs/waddles when the coop temp gets below freezing. I have 14 fully feathered hens (BA, RIR, BO & BR) and an 8x8 non-insulated coop with a ventilated ridge. I use a heated waterer so freezing water isn't an issue. A couple of nights I put a heat lamp in the coop but I noticed some condensation. I've heard people talk like condensation is a bigger danger to the birds, but I'm not sure why? How cold is too cold before I start having frostbiten combs/waddles. I'm new to this. This year is my first year for having chickens and I'm really loving it. Only want the best for my girls! What I need is advice from you.....people more experienced in raising chickens. I thank you in advance!
