Yesterday was day 25 so we did the float test and the egg wobbled, I made a small hole in the air sac, and we noticed that it looked shrink wrapped. So very slowly we made the hole larger. There are still big veins over the chick and it seems small to me? How is this possible on day 25? I put some coconut oil on the membrane to keep it moist, but I don’t know what else to do?
