I am new to the shipped eggs. I have a very good incubator ( GQF) that I have always had good hatches in so I thought why not try them. I ordered 22 eggs off of ebay. I let them set for 24 hours before I placed them in the incubator. I did not turn them for the first 3 days. ( big end up). I checked them at day 10 and all but 3 out of 22 have no air cell. Is that from shipping or just the eggs being old when shipped?
