Hi! New to BYC but not to chickens and ducks! Haven't hatched any eggs in years as I've been with out viable hens (our girls are old ladies now!) but... bought 6 orpington eggs off the internet for an experiment. First time I candled, 7 days, one of the eggs had a blood ring, but the rest were fertile and growing. The second time, 16 days, all was well again. I then left them til the 18th day, stopped turning and took the dividers out, upped the humidity from 50% to 70% (these have always worked for me before). Today I got up at 6am and had a little fluffy chick waiting for me in the incubator after pipping at 11am-ish yesterday, and then another hatched today at around 4pm after a little assistance from us. Now we have another egg that has been wobbling for three days now, no cheeping and no beak in the air sac, how should I help him out?? There is a crack in the egg from our first chick knocking it against the wall of the incubator ( he was very active!!). Its now the end of day 22 and I'm concerned that the egg shell is too hard or he is shrink wrapped or something awful! I was thinking of just helping by making a pip hole first and see how it goes from there? Thanks in advance for your help!!
