Well. Welcome to BYC.... Or sorta welcome for
sorta new!
Something is wrong if they wept liquid. What did you candle them with? Try a brighter light and use different angles. Some can be a bugger to see through. The darker the worse they are. You can try and see light and darker splooches those could be porous eggs. Or if you see "worm" trails they have weak spots or cracks.
Did you weigh the eggs before you set them in the incubator. If I am feeling ambitious I weigh every egg. Normally I just do a random sample so I can check weight loss. On 18 eggs I would do them all. Check the weight around day 14, you should not have lost around 10% weight. If it is over 15% the egg is too porous ( these are my numbers that work for me. I have no idea if others use they numbers. That does not mean I will throw the egg out, I will just up the humidity a tad.
Storing eggs prior to hatch is important. I might go over board a little, but I store mine on incubator trays so they are always turning just like in the incubator. Did you wash the eggs?
I know sometimes you have to either wash it or plant poop in the incubator. I wash and cross my fingers on those. I do not want the bacteria in my incubator. BUT know washing them takes the bloom off the egg. The bloom is there to help prevent harmful bacteria.
Fresh eggs are needed. I have not set eggs in a week, I have 35-40 to go in now. I have decided to go one more day. I am not sure how wise that is, but we had some very cold weather a week ago and the older eggs are most likely dead from freezing anyways.
Good luck! If they are weeping I would throw them out, you do not want that bacteria and yucky gas to kill your good eggs.
