i have two goose eggs in lock down. they were in the same bator with my chicken and duck eggs. today is suppose to be their hatch day, but there are no pips, no chirps, no shake or rocking. the duck egg in the same bator just hatched 5 days early. how much longer should i give the goose eggs to hatch. i candled them just about every night when i took them out for a cool down, development was on schedule, and they were moving around. i candled the day before lock down and there was no movement. one egg has a large air cell and the other normal. any advice would be helpful.
