Egg binding can be bad, sometimes...but not always. Each reptile is different. A bearded dragon won't die just cause it hasn't breed, thats a dumb myth. I would take your beardie in to see a vet to check for parasites or whatnot. They shouldnt brumate(reptile version of hibernating) unless the temps stay down below 65 degrees consitantly. What bulbs are you using? My little man Marvin was just under a reptisun 10.0 and the UVB wasnt strong enough so he got sluggish. Switched him to a mega ray MVB bulb and now he is a fuiesty speed demon again.
