Catching up on this thread and totally fascinated with the banter on humidity levels, weighing eggs, meddling vs. benign neglect.
This is only my second hatching using the brinsea mini eco advance. It went so well the first time, I am barely thinking about it now. As for meddling? First hatch last year, I had one chick that got "stuck" and I ended helping that chick out of the shell. HE was beautiful, but he had bent wing which is probably why he couldn't finish his zip. He grew big and beautiful but did not survive the winter. pneumonia I think, I nursed him for weeks but ended up putting him down. Moral of the story? He was weak to begin with and I now believe that nature will take it's course. I will not do any helping this time around.
That said, I just removed the turner, topped off the resevoir and put the 'bator into lock down. I have 6 of the original 8 in there, one I am 90% certain is a quitter, one I am 50% sure is also a goner. Now I am on Pip watch and I will NOT interfere this time.
