maybe the carrots. they really aren't all that great from what my research has taught me thus far. I know a lot of folks feed their Beardies carrots, but I'm gonna stay away from them or at least feed them rarely. Hope he's feeling better
Does it smell terrible if not could be your lighting or just something your feeding. Carrots aren't a staple just like once a week if your dragon likes them. I mention smell because dragons easily get parasites or high parasite counts. Usually a sign is runny or smell. Your pic doesn't look runny. Everything your feeding is really good like the Phoenix worms. Don't even think they would need a calcium supplement with being a high calcium food. crickets are ok but depending on the size of your little guy. Can be a pain to feed them off. Dubia roaches have four times the meat then one cricket. And very easy to feed off even hand feeding helps with a bond between human and dragon.
Had Dubia for a long time like a colony saved a lot of money. But went out of town and forgot about them and lost that colony. Haven't got them again have no way of payment buy things online. So back to overwhelming crickets lol.
