My bearded dragon is arond 10months, recently ive noticed he's making this clicking sound. Im not sure if he does it when hes annoyed or if maybe theres something wrong with him. i dont hear it all the time, he made the noise earlier when i picked him up, he didnt seem very happy, he puffed out his beard and started making this clicking sound. hes also made the noise when hes alone in his viv and not with his beard puffed out. He seems ok though, eating, basking and wandering around as usual. anyone have any ideas?
