Hi. I really know almost nothing about Jackson’s but do know that they can have problems with temporal glands filling/getting infected. There’s also things like mouth rot and respiratory infection that could cause him to keep his mouth open, along with mbd. More pics will definitely help. If you’d like you could also have your husbandry reviewed to make sure that mbd and other things can be ruled out. You’ll find the help questions here if you want to do that. Just copy & paste.

My Cham tongue issues so I am forced to hand feed, mainly dubias but also hornworms, superworms, every once in a while crickets, I want to start varying his diet more though.

Not tested for parasites, his poop is usually looks firm as in it keeps it’s shape, unrated are white as the moon maybe too white and sometimes a little watery

He was diagnosed with articulate gout 2.5 months ago. His tongue doesn’t work it shoots out only 1 inch, I used to not know what I was doing and I used to not fully give him best care possible which could be reason for some of his issues
