I recently bought two new incubators from an eBay store. I have now hatched out my second clutch of eggs. Both times I only got 7 chicks from 20 eggs and the last ones were very sticky. I bought a meter that reads temp and humidity and put it in the empty incubator and found that there was a wide temperature range difference. The incubator says 38' and the meter says over 50'. Now I am really confused! Which one is correct?? I appreciate any help I can get, cheers.
