I agree. I'm not giving up on them, I'll go to day 25 before that. Tomorrow if they haven't pipped I will try candling and if that's inconclusive I'll try the float test, but only with no internal pip. Friday will have to be the end as I'll then be out for the weekend again.No problem. I think you just have to read what you can and go with your gut. I am learning a lot through all of this. I know it will be disappointing for the kids if they don't hatch but you will just have to do it again and make some changes.
My temps dropped really bad when I took mine out of the turner and locked down and then I was gone all day long and didn't see it till I got home that night and then I was frantic trying to get the temps stabilized before I went to bed.
I had a hen a couple of years ago that decided to set on some eggs in the dead of summer, 110 degree days, no humidity at all. I go in one day and hear chicks peeping but nothing hatched out. I waited a while and still nothing and finally I asked someone I know that hatches all the time what I should do. I was always told not to help them out cause they wouldn't live anyway, he told me basically to help them cause they were going to die if I didn't help them so what did we have to lose. We helped anything that had pipped and only lost one of them.
I really don't think they are as fragile as we think they are.
So have you got to the hatch date for the one where your temps dropped when taking them out of the turner? That's exactly what happened to me, only from Friday at 3 until Monday at 7am It was at 92 when I came back in
