I'm assuming you set all those eggs at the same time? If so, the eggs that you can see light thru look like they have quit developing to me, early stage... the 2 darkest eggs (unless it's just the pics) look developed and fairly close to lock down time tho... do those 2 have slanted air cells? If so, that's a good sign, means the keets will pip into the air cell soon, then onto pipping the shell and hatching eventually (hopefully!). I know taking candling pics can be next to impossible, I've tried a million times over the years,with mot much success at all, at any stage! It frustrates me to no end.
With the eggs sitting on the bottom of the cooler/incubator floor like that they probably aren't getting enough air or heat circulation tho... so if this fails for you, maybe next time try raising the eggs up off the floor with a wire rack of some kind so heat and air can circulate all around the eggs. I add a small PC fan to each of my still air hatchers (to convert them to circulated air hatchers), with the fans mounted facing upwards at the top of the 'bator, but with 1/4" spacers in between the fan and the 'bator top so that the fan could produce gentle air circulation and not blow directly on the eggs. Your fan might be a little too big for that small of a cooler/incubator, even tho you do have the air flow diverted. I'm not laughing or sighing at you, just hoping you get a couple keets out of all that you've been thru!
