About two weeks ago I got a baby bearded dragon, he’s been doing really good he’s been eating moving around exploring, but a few days ago I noticed his color has gotten a little darker but at night his color goes back to how it usually is. I’ve been really paranoid because this is my first bearded dragon and I’m just worried about everything that’s going on. But since his color is getting darker. When he lays at his basking spot he spreads his back legs out and his eyes seem sunken in. And idk what to do to make him happy and comfortable in his enclosure. Please help!
