So I have a Magicfly 12 egg little oval incubator. I bought a thermometer and hydro thing to add to it. The problem is I can't get it to stay at one temp. It ranges from 97.8-99.4F. It got chilly in my house so I wrapped at towel around the bottom to help. The eggs are only on the 2nd day so are they ruined already since I haven't been keeping it 99 or higher?
