We had half a dozen bantam eggs in the incubator. 3 hatched and 1 survived. Then we had 7 that were due to hatch 4 days ago. Again, 3 hatched and 1 survived. This time I decided to investigate. What I found was that the little guys had pipped through their membranes, but they couldn't pip through the shells. Each and every one! I have 72 eggs in my incubator due to hatch tomorrow. Some of them are my own and some I ordered. I don't wanna lose them for the same reason, but I don't wanna help too early! I have also noticed that the shells of our "eating eggs" are extremely hard to crack, as were the ones I dissected today. What am I doing wrong??? I feed them Laying pellets, corn chop, and laying crumbles mixed together in equal parts twice a day. they also get raw fruits and veggies here and there as a treat. I used to give them oyster shell, but I haven't in a while. They sort of free range too. Continuous fresh water. Are they getting fed too much? Too much Calcium? How can I help these that are hatching? Better yet, when do I? I'm tired of dead chicks!
