I have bought eggs - my Delaware's were from E-Bay. They hatched out good I thought - 5 out of 7. I just got 10 turkey eggs and 28 quail from E-Bay. I don't know how well either of these will do. The pheasants I got are from Ova-bid.
It's pretty limited here in what is available nearby. It's fun to hatch eggs. Its fun to get chicks in the mail too. (Just got guineas and 3 packing peanuts). My post office is really nice and called at 6:45 to get me my chicks and keets and are really good about getting "fragile" packages to me.
I will say this, the eggs that I have received were extremely well packed. Styrofome packing p-nuts, bubble wrap, in little egg cartons, etc. And the eggs have arrived in perfect condition- from looking at them.
