I have a hen that was sitting on 5 eggs. Today is day 21 but 1 hatched yesterday morning. She has been getting off the next today with that one. One egg started hatching this morning and when I went back to check on it, she had been pecking at it and it was covered in blood and died. There are 3 eggs left that haven't started hatching yet and I'm wondering if I should do anything. Should I remove the one chick that's hatched so maybe she will stay on the other 3. Should I take the 3 eggs away as soon as they start and put them under a heat lamp?
