My hen Sadie is sitting on one egg. I've candled it and it is developing. . .or was. It's been 105 degrees to 107 degrees daily. The past week she is in the nest, but will not sit on the egg. She stands over it! It's just too hot! Will this kill the chick in the egg? Or will the high temperatures of the air keep it going? It's her first time broody and it took her a week to stop jumping from nest to nest, so I finally gave her one egg. She's been faithful now to sit on it until this heat wave, that is. What will happen do you think?
