Im still in my first year with chickens. We thought we lost a hen. But she showed up one day. I followed her to under the front porch. She has a HUGE nest! 23 eggs. We candled 2 eggs and we are guessing they will be hatching any day. I have decided to not let her raise them. My questions: Out of 23 eggs... how many should i expect to hatch? When should i remove the chicks from the mom? Thank you.
