My broody hen was sitting on 4 eggs - first one hatched Wednesday afternoon. Last night - chick was out of the brooder box and froze to death overnight....mom this morning had no interest in setting on the remaining 3 eggs (which were couple days behind the first). I have no incubator - always used the old fashioned method with letting a hen hatch them. Brought the 3 eggs in the house and placed them in a heating blanket.... Any chance they will hatch?
