It isn't your eggs, newly laid eggs dont really have air cells, the egg has got to age a couple days before the cell grows from moisture loss from evaporation, Drop your humidity to 30% for 5 days and candle again, looks like you are playing catchup on your humidity, oh, i can make out the air cell in the 2nd egg photo, it is about 1/2 the size of a thin dime, keep your humidity low, it is absolutely a fact you need to evaporate about 15 % of the water from the egg by day 18, everything you need to know about hatching is in this BYC thread, good luck and Happy hatching.
