I would leave the cloudy ones for now. Usually at this time they are either clear, or have a blood ring, or the yolk is shaken up and broken in shipping. I got some eggs in the mail that were wrapped exactly like that and they were beautiful. Out of 10, 2 were clear. It's day 16 and I still have 8. If I hatch 8, (fingers crossed), it will be the best hatch I've ever had.
But those temp bawbles make me crazy. I've been working hard to keep the temp between 99.5 and 100.5. I don't fool around with the temp setting anymore. I just add a lamp, or bubble wrap, or take it away and put the ceiling fan on. The weather here has been all over the place, from 70 to 40, humidity from 40-88% outside. I think there's more to a temperature reading than just temp and humidity. I'm sure there are some other factors involved as well that we can't change. Barometric pressure, atmospheric pressure, altitude. Still makes me crazy!
