I have 3 cayuga hens, 1 cayuga drake and 1 pekin drake. I put a round of eggs in the incubator and they're starting to hatch, but it looks like they can't get out. I've tried looking up what the humidity levels should be several times and it seems to vary anywhere from 45%-95%. Some said to spray the eggs with water when you turn them and everything else. Does anybody know what I did wrong or what I should do to have a better success rate next time? I had the incubator at 99.5 F the whole time with at least 55% humidity the whole time. I did not spray the eggs as I just saw that suggestion for the first time last night. I've had chickens (60,000) my whole life and have no problem hatching them, but apparently I don't know enough about ducks. If anyone can help, please let me know! Thank you!!!!!!!!!!
