My egg seems to be growing, I think it's still alive.

I've had it under the
Brinsea chick brooder in a basket with nesting. It's nice and warm like the hens' eggs.

The local wildlife rehabber here said it's a dove egg, not a pigeon.

The egg is halfway dark, with veins. When do I stop rotating and candling this egg? When does it go into "lockdown"?
I took these pictures today: Phone didn't want to focus, so it's a little hard to see details like veins. In this picture you can see how big the dove is, he's definitely grown since Saturday!
Not sure why there is this blank space--is it the air bubble or did the dove die??
Here you can see veins and the dove:
A little unfocused, you can see the fluid and part of the dove:
This picture is from last Saturday when I got it.
It has grown since:
Please let me know what you think! I've never rescued a dove egg before.
