NEED HELP!! Egg Problems!

Hey guys!

I am new to this site and pretty new to the whole breeding bearded dragon experience, (i've kept dragons for a long time but just now got into the breeding aspect of it.)
I really need some help. I have had my first clutch of eggs in the incubator for a little over a month now, and a few days ago I noticed one of the eggs was turning bright green (which led to it turning into a rancid brown/green color) and I figured that maybe the egg just died and that was no big deal. But now it's happening to TWO MORE EGGS!!! I'm freaking out! What am I doing wrong? I don't want to lose any more eggs!! I have been keeping the temperature of my incubator at 83-85 degrees and i've had the humidity in the upper 70's/low 80's.
Please help me, I would really like to know what is going on here!
Thank you so much!

what did the eggs look like when the female laid them?
