Hello all, This is our first incubator hatch, since our hens don't go broody anymore. We have a clutch of about 20 eggs in the incubator, some vary by a couple days age-wise, and last night 5 started pipping (on the 20th day). We left them alone, the humidity was only ~70% but we didn't want to disturb them - but today all but one has died! They managed to crack open parts of their shells, but only one so far seems okay. What do I do!? I can't just continue letting these little babies die and not try to help. Some seem to have a bloody/yolky film on them, does this mean anything? I can post pics of that would help.
