Either you calculated days wrong, temps were high, or someone sat on those for a while before you found them.
I'm not sure what is going on with them. I know I picked them up on a Wednesday and didn't get home until late. I took them out of the back of the truck the next day (along with all the chicken eggs that just hatched on time). I didn't end up doing anything with them that day and finally got them into the incubator that Friday. I origanlly had almost 7 dozen eggs so I don't know how all of them could have been sat on. None of the Turkeys have pipped yet and they were set the same day (I do see some of them pushing on the air cells but no internal pips yet). Very strange.
