I have a beardie named Henry, and he is less than a year old. He hasn't shed for MONTHS. He also hasn't pooped for WEEKS! It is winter, and he kind-of did a bit of brumating, but he woke up and hasn't slept during daytime since. Once he woke up, I gave him a bath and he didn't poop. I also gave him a bath before he went to sleep, and he didn't poop. I feed him a salad with romaine, carrots, fruit, and crickets dusted with calcium almost every day. He has a basking bulb above a fake branch where he likes to bask, and his substrate is excavator burrowing clay. For water he has a water fountain that he loves to lay in. his temperature for the cool side is 80-85 and his basking spot is 90-98 or so.
He looks pretty good in that photo. I'm sure the new T5 UVB will help his digestion and overall health. I would offer him drips of water on his nose to lick up and maybe offer some baby food applesauce or a few drops of olive oil to help things along. Overall it might be good to ditch the romaine and carrot in favor of things like squash and collard greens. I suggest limiting fruit to an occasional treat.
