Really tried hard on this set and have some shipped eggs in there. Candled day 18 and all in lockdown looked good...movement, etc. had some fluctuations in temp with the lockdown bator on the high side but for the most part it has been pretty good. Humidity around 50% checked with flashlight this morning and not one single pip. SHould have some pipping some sign on hatch but nope nothing......ugghhhhh!
