My cochin hen went broody and laid 8 eggs. She hatched out 3 and they are with her. One she hatched and I took as she wasn't taking care of and it is fine. Found a hatched chick dead and one that tried to hatch and was pushed out of nest and died in the egg and one egg not hatched yet. Is this hen just not a good hen to hatch chicks? Should I not let her go broody anymore or were there just too many eggs for her?
