Went back and recandled after some more reading.. Air cells of 5 are small and round. 2 I had a hard time deciphering bc the whole egg lights up so they may be duds or damaged or saddled or I just don't know what I'm looking at.

Now I really am going to leave them alone. Lol.
They roll a lot..-l read somewhere that someone put sponge pieces to hold them in place - tell me if that's not OK, I can cut paper egg tray in pieces or something.. have marked 2 sides soI can rotate.
Got paranoid re thermostats and hygrometer so have another one on the way.- paranoid bc the 2 Temps don't match. Humidity reading w/incubator off was 46%. House unit says that's abt right. The unit's thermometer is at the top below heat & fan, and is much higher than probe of independent unit on base. My infrared gun pretty much says both are right, depending on where I point it-higher at top and humidity reservoir in center, lower on base. But hasn't been running longer and I kept fiddling so-. Anyway, have manual one coming that can be calibrated as suggested (had already ordered digital before). The one coming sits upright on a base so will probably have 3 diff numbers now.
