Egg luck

[puffypoo]

Hey guys!
I just got some hens yesterday, and although we don't have roosters, the farm we got them from did have roosters. I want to try my luck at seeing if this pretty silkie egg may hatch...I would have the silkies brood it but first the egg needs to actually be fertile and second the hens must begin to brood. Unfortunately the silkie got out of the nest boxes after she laid but I have three other silkies,
So first is this egg fertile?
Second, is there a way to save the egg and wait until the hens start brooding?
Thanks!

Eta: I put the egg in the nest box and a silkie immediately went in and tucked it under her fluffy pants Still want to know if it was fertile
