I had a broody hen. Gave her eight eggs to sit on. Only two of the eight hatched out alive. We had two babies to hatch out Still born, and one that was deformed and did not hatch out at all.the other two were duds . Anyone have any ideas why all this would’ve happened? The eggs came from a flock of about 25. There are two roosters on site who know how to do their job well. We dusted all the chickens about four days before the chicks hatched. Could this have anything to do with that?
