got a hen with a potential mouth infection? help please!

[Rand0]

I have a hen (3 years of age) that has suddenly started to start gaping and wheezing.i have tried vetrx (gonna switch that since it didn't help) and her tongue seems discolored and her breath sure does stink. I'm sure it isn't her crop since it empties and is full at night and she hasn't lost and weight and she feels okay all around her body.does anyone know what could it could be?

What's her crop like?

Her tongue does look discolored, have you pulled any lesions or pus off of it?

I do see what may be some lesions/canker in the beak and down the throat.

If there's a bad odor, then you may be dealing with Canker. Treatment is with Metronidazole or Acidified Copper Sulfate.
