i have a lone egg in my incubator, the others died early but today is day 20 and i just cannot resist to candle them. (i know i should not, but only did it once haha ) now here's the thing. the chick is moving! but the aircell is almost half of the egg and crescent shaped. should i worry? i saw some pics of day 20 eggs that has way smaller air cell than mine. will my chick be alright? :/ i just cannot stop thinking about it. and btw, this is my first hatch! (hopefully) thnks guys!
