So the good news - we got our first egg today! Bad news - it looks like one of the ladies has frostbite. Which is kind of shocking to me, as we've only had maybe two overnight frosts, and no hard freezes yet. Daytime temps are 55-65, nighttime low 40's to just at freezing. But she has black tips on her comb, and has the largest comb of the bunch. Today there was a small droplet of blood on one tip too, I think (moves too much to tell for sure). Is there anything else this could be? Not thinking it bodes well for an upcoming predicted very cold/snowy winter. We just insulated the ceiling this weekend (not doing walls). I also put plastic over four of the six windows, leaving two large open vents (about 2' x 8' each). Deep litter, roost of 2'' x 4'' lumber. All else I can think of is moving the nipple waterer outside, or possibly horizontal nipples instead of vertical. Or should I take some of that plastic right back off?
