I have a 15 day old viable egg in my incubator, in a turner, and found that the air sac is in the bottom(small point) of the egg. I candled it and the chick is moving around. My question is: on day 18 when I take it out of the turner and lay them in the incubator for lockdown whill this chik be able to find the air sac. or is there something else I should do now. Thanks.
