I get 90 to 100%... but that's on home grown eggs..
last year I bought some shipped turkeys eggs..
first shipment was in really bad shape (lots of cracked eggs.. loose air cells).. out of 11 eggs received only 2 of those hatched.. most were scrambled in transit (18% hatch rate)
second shipment was 19 eggs.. 14 hatched (74% hatch rate)
you will find that some people have really low hatch rates because they incubate with too high of humidity (and too low at hatch).. so you'll have to take that into consideration since it's a very common error and will really bring down the average hatch rate
I had really good hatches with home grown eggs but not so much with purchased eggs, they weren't shipped, I drove about 1 1/2 hours to pick them up but had really bad results. Does any type of transportation decrease viability?
