Hi. This is my first time hatching and I'm using a hen. She got spooked by something today (day 20). One of the eggs was crushed. Fully developed chick ready to hatch. Poor little thing. I candled the others to make sure they were okay since they were all over the nest. They appeared okay at the time.I checked on her again before dark and two of them seemed to have a fluid moving inside. I could see the chicks outline well but there seemed to bensure fluid moving as a tipped it very slightly to see if the chick would respond. I hope they are okay.
