I have a Genesis 1588 and moved 36 out of 39 eggs to the hatcher this afternoon. IOnly 3 were not fertile!!! My question is this: How many are usually safe to put into the hatcher? The ads say up to 50 can be incubated. I put the eggs in 3 egg cartons with the lids cut off and the bottoms cut out. Another question.... what percentage of eggs can be expected to hatch?
