Got a question for y'all. I have 2 eggs outta 4 that made it to lockdown on 18th day of incubation. They arenow on day 22. Last night, end of day 21, one started moving and rocking the egg. The other hasn't showed any sign of moving, so I candled both no internal pip, tapped air sac no peeps. So I placed egg in warm water it floats and shows slight moving in water. So seems both are still alive. Although one has bigger air sac..the one that has been moving since yesterday. My question is, How long to wait before checking to see if they're positioned correctly? I want to let them hatch on their own, if possible, but am ready to intervene if absolutely needed and possible to save them. These are not chicks for a breeding program or anything, just a couple from my own flock. I just enjoy raising and hatching and am new to incubating. This is only 2nd time for me. I also am teaching my children and edcutating them on development process along the way. Any help is appreciated.
