The orange may just be from a bit of dehydration if it is attached to the urate. How often are you bathing him? Also, you are really underfeeding him. A 5 month old should be fed as many crickets as he wants in 10-15 minutes, twice a day. That could be about 50 or more. Also, kale is really not good for them either - it binds the calcium, so your beardie cannot absorb it. This can cause lots of problems.
