question about my eggs.

ok so the female beardie I took in 3 weeks ago laid her eggs on my dogs birthday (Monday). There were 21 but two accidently got busted by me when I was moving them to my homemade incubator. Some of the shells seem very thin even though I gave her calcium 4 days a week and fed veggies high in calcium. she also has a brand new uvb light. Some of the eggs look yellowish and there is a sort of "musty" smell in the incubator. it is set at 83 degrees and the humidity is at 85%. any ideas. three of the eggs looked to be dented in this am and I added some water to the substrate (I had eco earth on hand and mixed that with some sand and vermiculite which I found in a few places works for some people) any ideas. I know that this girl has been bred as she was living in the same cage as a male for 2 years before I got her (she is 2 now). I am hoping that these are duds but am incubating just in case. Any help would be appreciated!
