I bought my first fertile eggs from a BYC auction. They came in Packaged BEAUTIFULLY. I had my incubator tuned in perfectly before the eggs got here and even bought an egg turner this time around. Yet I still only got 5 chicks out of 14 eggs. I have success fully hatched out some of my own eggs at a rate more like 90% previously. Is this just part of hatching mail order eggs or was I unlucky?
