The reason I'm asking is because it will help to determine what humidity will work best for your incubator. If the humidity was too high during incubation it can cause what's called sticky chicks and they won't be able to turn properly in the egg to internally pip. In which case I would completely dry incubate for the first 18 days in your incubator or if it runs super low with no water then I might put in just enough to get it to about 30-35%. Once you get to hatch day, same thing, try running lower humidity, I've never done lower than 50% myself but it's a good starting point, if you see the membrane turning brown at the pip point then you could slowly increase the humidity to about 60%. Since you're having issues with fluid build up in your incubator I wouldn't go any higher than that. I hope that helps!
