Bird Watching: Am I Going To Be a Bird Daddy?, 1 by Amargia

(Jim) I found this egg nestled in the mud near my driveway after a bad storm. There seems to be some movement inside. I think the occupant might still be alive. I could find no nest in the vacinitly to return it to. At the moment, I have it in shredded newspaper warmed by a lamp.

Ironically, I was just taking a break from building a birdhouse when I found the egg. I love watching birds, but I can not claim to know that much about them. Does anyone have any advice? Is there a way to know for certain the egg's occupant is still o.k.? Would it be cared for if I slipped it into the nest of another bird? I was building the house for a sparrow who insist on trying to nest in my workshop. I thought if I provided her with more luxurious accommodations just outside, the shelves in my work area would lose their appeal. Could I slip it into her nest? Is this s sparrow egg? Any info would be appreciated.
