ok, i candled last night (day 15) and my air cells are different sizes... like some are small (not too small, i don't think...) and some are way bigger. what should i do, if anything? oh and ftr, they were shipped and some if not most had disrupted air cells when they arrived. they are all australian spotted ducks if that has any bearing on the answer. all 11 eggs are developing well, i tossed two previously (one clear and one quitter). so.. thoughts on the different sizes? what causes that?
