Mourning Dove Egg help

[Hailie101]

Both parents abandoned their nest yesterday. I brought them inside they look to be only a few days old. I have them on a lamp that's about 87 degrees right now, hand turning every hour. One looks to have significant growth compared to the other. The air sac is on the upper side a little bit but it doesn't wobble or move. There is a little ring around the veins and embryo. Does it look healthy? Also, one side is empty is that normal?

Now there's a white spot in the air sac..im guessing this isn't
normal?

Pigeons and doves are among the hardest to successfully raise from hatchlings bc for the first week the parents produce an extremely nutricious substance known as 'crop milk' which is important for their development.

Welcome to BYC, anyone who has an egg candler belongs here!
