Ugh. I just noticed today that our hens have been sneaking their way through a hole between their side and where we have our 12 week olds, and eating the medicated chick starter. I have no idea how long this has been going on. Should we toss all of the eggs we have?
such a trooper!
Definitely calibrate! My genesis ran perfectly off the factory thermometer last year, and was 3 degrees off (low) this year. I calibrated a cheapie aquarium thermometer and checked the temp against that and haven't had any incubator issues since.
