novital covatutto 7 incubator

[Kymw90]

Ok so second day of incubation of the guinea eggs. I have 6 in there all numbered for when we start candling at day 7. So my question is.. Has anyone used novital covatutto incubators? Especially the little ones that look like a bubble. The one I have exactly is a novital covatutto 7 with manual turn. My problem I'm having is humidity? I have filled half of one of the 4 little square wells and can see a bit of condensation which I know is not a good thing. I did a bit of reading and a few things came up saying don't pay attention to what the instructions say about humidity levels.

Can anyone tell me what they have done with this little incubator for humidity purposes? What humidity should guinea eggs be in?
