Sick Beardies pls help

Hey all I have a juvi bearded dragon I have had him and another from the same clutch for about a month now one is doing fine, but the other has not really grown just gotten fatter, and now is REALLY sick he is extreemly lethargic he will perk up his head and just kinda fall back over and just lays there, I put him in his water bowl he drank some water and I picked him back up and there was a tiny bubble not sure why, he seems to have a very small cut it looks like on his underbelly and his vent is dirty, I feed him the smallest of crickets they get dusted once or twice a week he has 7% UV 12 hours on 12 off and warm spot in cage temp is 110, please help........


also I have 2 other juvi beardeds about 2 months old that seem to have a similar problem loss of appetite loss of weight almost always dark in color, seem to be getting a little lethargic, they recieve the same care as the beardie listed above.

help please!

The best advice I can offer is get them all to a vet immediately. What your describing is far beyond what a simple answer from any of us here on the forum could fix. You need a professional to give you a hands on diagnosis and treatment plan.
