Pekin duck by the way. First you need to check if it's fertile, go to a dark room and put a flashlight under it. If it's fertile, then you see yolk in the middle of the egg perfectly round.(You can google for a image) If you see nothing or just dark spots(pores) then it's infertile. If you have a fertile egg, here's a expensive part. You HAVE to have a incubator to hatch it. You can hatch it with a heat lamp or anything, it needs to be the exact temperature constant and the exact humidity. incubators can be expensive but you can make it yourself by googling or find it on youtube. If you can't get a incubator and can't hatch it, give it to a local farm or post it on craigslist. Good luck, oh and it can't die since it's never been developed yet, it's still just a yolk like the regular ones you eat every day so don't worry.

So my sister and I were at the park and they have this petting zoo type of thing but we saw a big white duck (I don't know what type of duck breed) and the duck laid an egg right in front of us and she just left it there in the shade so we picked it up and took it to the park people and told them what had happened (because we didn't want some one to step on it) so the park people said we could keep it or leave it there but the pig there would eat it so we decided to keep it but we don't have any idea what to do but were keeping warm just we need directions on how to keep it alive.. Please help we dont want the poor duck to die
