My first broody chicken's eggs started hatching yesterday afternoon! They are JG and JG/BO crosses. There were 4 alive under her this morning and at least 1 more pipped. Thats all I could see before she jumped back on. Unfortunately, 2 died while hatching. She had 12 eggs under her when she went broody but when I looked under her yesterday, there were 20 eggs. So, either she stole eggs or someone else was laying in there with her. I was able to remove 6 that were infertile, not far along or had not made it. But I have NO idea how many of the eggs are viable.
