I am finishing up my first incubation and I have 2 eggs that are 3 days late - yesterday there were 3 that were 2 days late - and one hatched mid-afternoon yesterday. It seems to be OK so far. It's eating I think. Can I -or should I- break open the shell in the air sac area on those last 2 and peek in to see if they need help out? I've had a heck of a time trying to keep the humidity up to even 65% and have had to open the incubator every day to add water.... Are they done? or dead?
