My broody hatched one chick a few days ago and got off the nest with the little one today. She did go back to the nest then and tucked the remaining three eggs underneath her. I checked the eggs and they were not "cold" but not very warm anymore. Are the eggs still viable for hatching? I have another broody get off of her nearly ready to hatch eggs and go sit on a nest of just laid eggs. I took those eggs from her and put her back on her own nest. Her eggs were also cooling off and not very warm anymore. I assume if these eggs don't hatch in a few days, the won't ever hatch. How cold can an egg get and still survive? All of these eggs should hatch any day now.
