I never heard what type of incubator OP was using. That itself is important. Before we even go any further really .Some wafer thermostats are great. Some are not as exact.I have one going on four years in a hovabator. They are only 6 bucks so I bought a coupla extras just to have on hand. Now any way I looked at it I can only see a forced air of any kind not affecting the temp as she claimed unless helping it stay More precise as Tony KT pointed out. Also like Bluegoose said. The room temp around the incubator affects everything unless the thing has about 12 inches of insulation.
Ive never had a problem hatching pheasnt eggs as opposed to quail though. You seem to think it is not a bacterial problem though Missred871 but at the very least I would clean the bator then you definitely know that isnt it. Because if you been hatching out alot with no problems this is what I would suspect first or check your thermostat second whatever kind it is. I personally think these are the main two issues of incubation problems. Also like poultry Rocks said There aint NO guarantee on shipped eggs for sure. Hope you get the problem solved and if you do let us know what it was.
