I'm currently trying to set up my incubator. I'll soon be receiving Eggs by mail and would like to get the temp fluctuation issue sorted out before they arrive. I have RITE FARM 3600 Pro force air incubator. With the incubator set on 100 degree F iit will spike to about 102 for a very short time then fall back down. Also with it set at 99 it will spike to about 101 for a short time. I currently have 2 thermometers in the incubator that are reading the same but different than the one on the unit. I I've set the unit to 98 and it will spike to around 99.5 and will bottom out at 98.2 before coming back on. I guess my question is is this acceptable.
