Yes, as soon as I read your temperature of 86 degrees as a high it was quite obvious why they were sick. As AHBD already said, I hope they are not already too sick from the combo of living in 86 degrees and getting 2 baths a day...not good.
I hope that you can get their Basking Spot Surface Temperature more steady, as 45 degrees is too hot, and having a temperature of 40-45 degrees is not good, it's needs to be much more consistent, and not go above 43.5 degrees. The reason i'm making a big deal about this is because they have not eaten anything yet, and they are already way too dehydrated, so if their Basking spot Surface Temp gets up as high as 45 degrees, this could be literally fatal.
And please, please, don't simply "Mist" them right now, that's not good enough, you need to drip water on each of their snouts individually, let them lick it off, drip, lick, drip, etc. and allow each to have as much water as they want, only stopping when each baby stops licking it off or walks away. You have to realize that they have gotten no food since they hatched, which also means no water, and they're going to die if you don't MAKE CERTAIN that these 6 babies start taking in adequate water through their mouths at least 2-3 times a day, and "Misting" them is not going to do it. You can start "Misting" them 2-3 times a day ONCE THEY START EATING LIVE INSECTS, but until that happens, you must start dripping water on each of their snouts and give them as much as they want 2-3 times a day. You can mist them as well, but please take the time to individually give them each water 2-3 times a day until they start eating the live crickets, as this is the only way you're going to keep them alive at this point.
Hydration BY MOUTH is much more important right at this moment than the nutrition is, that will come with you finally getting their temperatures correct, their UVB tube within 6" and not obstructed, and you completely stop all the Baths! (I FORGOT TO MENTION, I THINK, MAKE SURE THAT THE FIXTURE YOUR UVB TUBE IS IN HAS NO CLEAR, PLASTIC COVER ON IT'S BOTTOM, AS IT LOOKS LIKE A ZILLA SLIMLINE FIXTURE, WHICH USUALLY COMES WITH A CLEAR, PLASTIC COVER SCREWED-ON THE BOTTOM WHICH COVERS THE UVB TUBE, AND BLOCKS 100% OF THE
UVB LIGHT, NO
UVB LIGHT PENETRATES CLEAR PLASTIC OR GLASS, SO PLEASE DOUBLE-CHECK THAT AND REMOVE IT IMMEDIATELY IF THERE IS A COVER)...
******Also, I would move the UVB tube more towards the middle of tub, away from the side of the tube, as you're losing some of the
UVB light right off the side of the tube. Be sure that you do go out and buy a Halogen Indoor FLOOD Bulb...I'm glad AHBD pointed this out, as I hadn't seen the photos when I posted the first couple of posts, but you cannot use a SPOT Bulb, as this is why your Basking Spot Surface Temperature is so inconsistent, it's focusing the light/heat on one little spot/area, and the rest of the tub is whatever it is, definitely too cold. A Halogen FLOOD Bulb will keep the temperature consistent and the entire tub warm. This way they will all get bright-white light, heat, and the UVB/UVA light at the same time, which is exactly what they need...
******Something else that is going to be extremely important, you mentioned that you have 20 more fertile eggs going to hatch, PLEASE DO NOT PUT THESE NEW BABIES IN WITH THE 6 DRAGONS THAT ARE SICK...First of all, you need to keep them separate so that you know which ones they are, so you can keep providing them adequate
hydration by mouth 2-3 times each day, and you absolutely must keep very close track of how many crickets they are eating. In addition, these 6 little guys are already extremely stressed out and need to be able to eat the crickets freely, without competition, and if you throw-in more babies with them it's going to cause them far too much stress and will keep them from eating...You have to realize that now that you know what you were doing wrong, the rest of the babies that are going to hatch are going to be kept in the correct temperatures, UVB, etc. right from day 1, and they're going to be eating tons and tons of live crickets and be healthy and active...So if you throw them in with the 6 sick babies, they are going to completely dominate them, take all the food, they'll drink all the water when you mist them, and they will just totally overwhelm them. So you're absolutely going to have to set-up more plastic tubs with more adequate UVB tubes and bright-white Basking Bulbs over each tub, that's just what you get when you breed them...I'm assuming you're prepared already with several other plastic tubs, UVB tubes, Basking Bulbs/Clamp Lamps for them, etc., but I just wanted to make sure that you are fully aware that you absolutely cannot put any of the other babies that are going to be hatching in with these 6 sick ones that are going to continue to need special attention and care, and that cannot be dominated or overwhelmed by other healthy babies who will eat all the food and drink all of the water, etc.
