My female beardie looks like she may have a mouth infection. Here beard is swollen...not the normal beard puffing...but when you touch it is is somewhat firm...

Other than that she looks very healthy and is eating well. She laid a clutch a couple weeks ago. I don't know if she has just chubbed out or what - but i haven't seen it like this before.

The cage setup should be perfect. I have heard that a swollen neck might indicate MBD but that would really surprise me.
