My BPR became broody on Dec. 20. After almost two weeks of trace-like dedication to sitting, in the last few days she became much more interested in going out of the nest and staying out--scratching for worms. Eggs got cold a couple of times, but we got them warmed back up and by pushing her gently towards the nest box got her to sit again. Today I checked her every hour or so. Eggs seemed warm until this afternoon She had broken open one egg and the rest were ice cold. Looked like a murder scene. I rescued the remaining four, put them under a lamp, and drove to Tractor Supply to get an incubator. BPR was still having broody aggression towards the other girls but I think the rooster sorted it out, and she's back in the coop with the others tonight. I really wanted to do this the natural way, but it seems like it just didn't work out. Perhaps she was starving and out of pure self-preservation gave up on sitting only 4 days from hatching. She is awfully light and her comb and wattles are several shades paler than her BPR sister. Hoping that we'll get some chicks out of this clutch, even if I have to do it the artificial way.
