Using heat lamp to hatch day 21 egg

[crazychick87]

Our broody hatched 2 eggs yesterday (day 20). Now day 21 there is one egg left but she’s not interested and constantly off the nest now as the day olds are running riot lol. Question is, I have a heat lamp, could I put egg under the lamp until it hatches? It does seem to be alive in there! I know many let nature take its course but I’d like to try and give it a chance if possible.
Thanks

I’m so sorry. I wish I would have seen it earlier.
