Hi my bearded dragon Charles has not pooped in about 15 days and I feel like I have tried everything. He usually only poops outside or in water. I have been giving him prunes, pumpkin, and olive oil to try to make him poop and he still hasn't. His energy levels seem the same and he still eats live prey but he hasn't been eating his greens. I've been giving him baths and massaging him but still nothing. It's currently winter here so I can't take him outside. Any suggestions would be helpful
