No, Unfortunately they are not. You have to just sit out the incubation time. Which is interesting too. Because the fertility of these eggs is 100%.
The thing about these eggs I have found is they need 24 hours sitting after shipping to be sure the air cell stays put. Shipping seems to cause them to come loose.
So if you get some of these eggs. Remember to let them sit for 24 hours the air cell will reseat itself and if it doesn't and you get no chick... you didn't need to have that problem. Thats the way I see it.
