I have a broody hen on a number of eggs, she's quite an aggressive hen so we don't get to check the eggs so we just let nature take its course. We witnessed one egg pip yesterday morning and it was chirping through the gap before we left for the day. I've checked again this morning while mum was out and there is no sign of this egg or a chick. I tried to check all the eggs and couldn't find any with a hole. I also couldn't find a dead chick or any remnants of its egg! I need some advice on what to do if mum is homicidal as we currently don't have an incubator and the eggs are all at different stages (some aren't hers).
