Sure is.Is that one of those cheap Chinese ones?
no I haven't placed any eggs into the incubator. I decided to do a test run for a few hours. thanks for your suggestions.Sure is.
OP, those incubators are known for being bad. I would try to return it. If you already have eggs, you may want to try and borrow a better one. I've never known anyone to hatch a single thing out of those. They're "death traps" so to speak. They spike and fluctuate so bad it kills the embryos.
