Today is day 21 for my d'uccles (first batch of bantams). The first chick that pipped had zipped and then died, that has never happened to me before. One hatched but seemed dryer than my previous hatches. I had another zip (about 24 hours after pip) and didn't seem to be getting anywhere. I helped him out and the membrane was really stuck to him. I incubated at about 40-50% and at lockdown have been a constant 65. Since they seem dry I increased the humidity to 75-78%...is this ok? Is there anything else I should do for these dry babies???
