My last hatch, I had a single chick, hatch 3 days before the others. I had not yet even removed them from the turner !!! We had been in the middle of a record heat wave, so I wasn't sure if the postal service had begun incubating for me, or if I had a hot spot in my hovabator. Since then I upgraded it with a internal fan kit. Heat really seems to be ALOT more consistant then the last time. Locking down this evening for Sunday hatch. And no early babies this time !! Let's hope for a fruitful Sunday shall we ? Good luck all ye hatchers of the peeps !!!!
