My first broody hen....chick was breaking through around 2:00 today, by 5:30, I checked again, she was sitting on it and the other eggs, but the chick was half out and dead....did she suffocate it? Was something else wrong...? I have another one due to hatch out tomorrow morning...do I need to do something to prevent this again? She has 3 other eggs under her, we are at day 21 now. I don't want to lose all of them. I have another hen sitting on 7, due to hatch in about 10 days....is there something I am doing wrong?
