An eggs viability drops after 15 days,but during storing them before putting them in the bator,they still have to be turned 3 times daily and stored in a cool place.This is for pheasants,quail are a little less storage time.I use an automatic turner for stored eggs so I don't forget to turn them.Shipped eggs are a whole different story.Shipped eggs get pushed and jolted and maybe even x rayed during shipping which will effect hatch rates.I don't believe in shipping eggs for this reason.If I want a certain bird,I will buy that bird,not an egg to have a chance of having that bird.If you add up all the money you have tied up in eggs,and then see what you have for birds from those eggs,you will have bought at least 10 pairs of that bird at the end.Spend the few dollars more and buy birds,do not waste your hard earned money on eggs.All it takes is just one good jolt to kill the embryo and all is lost.Red golden eggs sell for about 3.00-3.50 each,so that's 36.00-42.00 per dozen.A juvenile pair of goldens are about 40.00 pr.plus the shipping cost if you can't find them locally,but you have the birds the eggs you still need to hatch them and after 25 days there are no chicks it can be disappointing.
