I'm curious as to why my Sulcata is making small movements with his beak (mouth) and slight noises when it's soak time. It's as if he has a nervous tick when he's in water. Is it his way of "calling out" like he doesn't want to be in the water? He only does this when it's soak time daily. He also does it above water, so it's not him drinking it. Anyone seen this before?
