Two years ago I got a hovabator from a friend who couldn't hatch anything in it. I said I would help fix it for her and now I have an almost 100% hatch rate on farm foul. The problem I had was the temperature in the hovabator fluctuating. I researched and found a forum that told me to duct tape a penny to the bottom of the incubator's wafer. I tried that and now my temp. stays at about 98•F-99•F. I recommend that people who have problems with their hovabator's temp. fluctuating, do this to their hovabators. It's a great way to fix it. Also, if possible, use a fan to circulate the air in the incubator. It helps a lot.
NOTE: I've had better hatches with the dry incubation method, you can learn about it here: https://www.backyardchickens.com/a/how-to-incubate-hatch-eggs-using-the-dry-incubation-method
Dry incubation, if tweaked, can work for waterfoul.
Hope this thread helps fix your problems
