Hi, i am having trouble getting my pecan and mallard duck eggs to hatch. They have been in the incubator for 35 days now and they still haven't hatched. I know they are not dead because they have been moving when i candle them. I candled one earlier today and it was moving and you could see the beak. I put the egg up to my ear and i heard pecking on the shell. i am wondering if it is trying to hatch and it can't get out and if there is anyway i could help them?
