Ok, so I borrowed a Hovabator circulated air incubator from a friend who has several to hatch a dozen or so shipped eggs. This is my first incubating experience on my own, had my hens do it for me in the past. Anyways, this friend told me the incubator was tried and true, everything worked great, yada, yada. Well, we are 9 days in and she calls me in a panic. She had sent me home with a faulty thermometer by accident. I rushed out and picked up two new thermometers (different brands, I wanted several opinions at this point) and stuck them in there with the old one to gauge how off it was. Well, according to my new thermometers (who read the same within a small fraction of a degree), the super fancy faulty digital thermometer ranges being off 3 degrees in either direction, apparently according to its mood. Uggg. I had been watching this incubator like a hawk these first 9 days, making small adjustments to coincide with what the faulty thermometer was reading. Tell me the honest truth, is it over? Will that degree of variation early in incubation result in defects in chicks should they even hatch?
