Today when I went to check for pips or hatches I found one egg that all the shell was broken off but the chick was still inside cased in membrane. The chick had not tried to hatch it was still curled in the ball I found a fully formed chick half the yolk asorbed but dead. I have no clue what happened because lastnight I counted her eggs when she got off to use the bathroom and all 7 where ok. Did my hen do this? I checked the other eggs and saw some pips and could hear the chick peeping inside I only candled once on these eggs at day 7 and all were growing.
