Glad you threw it out. I learned that an oozing egg meant that it is rotten and about to explode. Next time you see it ooze, just double bag it carefully and throw in the trash.
I have a
Brinsea Mini Advance and the instruction manual is rubbish. Go to this site and check out this lady's youtube video on how to set it up, and just do exactly what she does.

(Note though, she starts periodic cooling from day 0, but the
Brinsea manual doesn't recommend that you start it till day 7. To do this, you set it to off on day 0, and turn it to on on day 7, or just leave it off the whole time.)
For humidity, just put water in one of the two wells inside the incubator, and make sure it doesn't dry out (how much water doesn't seem to matter because it just evaporates off the surface, just make sure there is water in there). On Day 18, fill BOTH the wells with water and make sure there's water in both. You can open the top quickly to refill the water if you want.
Check out the website I posted and if you decide to do this again, follow her instructions exactly, and I think you'll do better. I used mail order eggs and had a pretty decent 50% hatch rate using the
Brinsea.
Good luck!
