I have one egg in an incubator and it is at day 19, I candled it this morning and it was moving so much!! It's been in the incubator for 3 days, it was under my broody for 16 days, and then I switched. When I candled it, the airsack was huge. The humidity is 80% and the airsack is bigger than it was 2 days ago!! Is the chick going to be alright? And will it hatch tomorrow or the day after? (It's squirming a lot).
