i've hatched three times. batch 1: i was using a diferent bator but it was a little giant too. Results: a great hatch, all but 7 out of 3 dozen hatched. batch 2: i wasn't using the same bator as b4 but is was still a little giant. results: the worst is history. Batch 3: using the same bator as batch 2. BUT diferent humidity. Results: 1 poor lonly chick hatch but out of 4 eggs, 3 made it to at least day 17. I don't get it!! why can't i ever have a succsesful hatch!!
