Abandoned egg

2 weeks ago, I took this pic when seeing the bird mother hatching eggs on the nest. It was just on a tree behind my house. Unfortunately, a week after that mum told me the mother bird left and never back because the kids played around the tree. since then, I took the egg and trying to hatch it myself by putting on a bulb. Anyhow now, I have a mix feelings on it. I was asking myself, should I hatch it or just left as it is. The more I think, the more I feel that I shouldn't do this. The nature has its own way to create or eliminate life, which human shouldn't interfere it.
