Hey folks I'm am about 1 weeks into the incubation period. Luckily I have two hens sitting on the same nest... a clutch of 20. Last summer the same two hens went broody together. But when the eggs started hatching the eggs ran into some problems. That would start to zip but the shell was to dry/hard. I lost 8 out of 25 Because they could get out I had 12 that I had to help hatch and 5 that done just fine on their own. The ones I helped I peeled off little pieces of shell and under the shell the membrane was completely dry sorta like leather. How can I prevent this and have a more natural hatch?
