Read about the dry hatch method, it is what I used, not saying it will be what works for you, but gives you some ideas on what others have tried with success.
https://www.backyardchickens.com/t/546026/anyone-ever-try-the-dry-hatch-method-before/50 Your humidity being high now could be due to the fact that the eggs have a lot of moisture inside them, is ok, just check and mark those air cells to make sure they are getting bigger as the days go by.
Wish I would have kept notes on my hatching, but didn't, I do know that I kept my humidity in the bator around 45, but would drop down to the 30's sometimes, also, we had a ton of rain during my most successful hatch, so may have been more humid inside the house during that time. It is very difficult to get that humidity up for the last three days here in our high desert, I used (2) bowls of water, all the trays were filled with water, and at least three sponges soaking wet. It is a science, so you have to be somewhat precise.
Hope you get a decent hatch with the local eggs, much easier than dealing with shipped eggs. Read all you can, you will find what works best for your area, your house, etc, and stay with it, don't give up, if it was easy everyone would be doing it! lol
I know never enough hours in the day, and you were covering a lot of miles that day!!!
