Sadly must report that I've lost two d'anver pullets since Sunday. The first was completely my fault... I set the feeder on the poor thing. Then I lost one last night. It looks like the others trampled the poor thing while they were trying to keep warm. I cleaned out the coop (which, for some unknown reason, everything was frozen. We have awesome ventilation so I'm confused how even just clumps of straw are being frozen together...) added over half a bale of straw and am now praying for the best. Any suggestions to keep my little ones warm?
