Mourning Dove Egg

Question
I already asked some one in birding, but I thought I should get another opinion. I know you don't want anything about pideons or mourning doves, but you where the only one available.
OK, I found a mourning dove egg on the ground at my cousins. I thought it was dead, but I decided to try it in my incubator (I breed reptiles). Its been in there for almost 7  days at 100 degrees F and still doesn't smell. I have been turning it 3-5 times a day. Does this mean it might hatch? I have looked up caring for mourning dove eggs and youngsters, but I was wondering if anyone had some advice. I was also wondering (if it imprints on humans) if it will come back if we let it outside, like a pidgeon. We have a shed where we could put a nesting box for it to roost in. Also, if it is a female and becomes gravid, will it come back to us to lay her eggs? And if it were a male with a mate,would both of them return to the nest box provided?
Keeping it inside when it grows up is not an option, but we have a fairly large rabbit hutch outside, so maybe it could live there? Or maybe we could put it there just for the nights? I've never kept birds before, so any help would be much appreciated.
Thanks,

P.S. I read that it is illegal to keep mourning doves as pets. If its not in my house, does the rule still apply? Also, will it come back like a homing pideon?

Answer
If it born in captivity is becoming legal under some situations. It has the lowest status so if you are planning to reintroduce it to the wild and doing to keep the egg alive. Then nothing very illegal you are doing.

I have done some research about keeping birds on the red list and other which conditions you are allowed to keep them.

Making photo's of it when it come out of the egg helps.

Also looking up the facts about the normal doves helps. I aspect that the facts and numbers would not very different.

The chance of success is there and keeping doves is not my speciality, but others have a lot of knowledge about them.
