Beardie foaming

Question
I have a beardie about 7 years old he has recently started producing foam at the edges of his mouth. He also has slowed down on his eating.

Answer
Hello Rich,

What is your tank setup like right now?  What type & brand of UVB light do you use, is it a flourescent tube bulb or a compact/coil light?  Do you use a bright white basking light?
What are the temperatures in the tank, & what type of thermometer do you use?  A stick on type, a digital probe or a temp gun?
Do you supplement calcium 3 times per week?
Can you post a picture of him for me, that would help me alot.  He could be slowing down for brumation this time of year, but, if he is acting ill, then, he probably is not feeling well.  Foaming at the mouth is not a good thing either.  A respiratory infection comes to mind.  Does he have any mucous in his mouth or nose, or just discharge or foam?
