Wet Fowl Pox???

[Rhythmoflove_11]

Millie has seemed like she can’t eat recently. Will open her mouth like she’s struggling to breathe. Has lost weight. Looked inside her mouth today, and this is what I see. Has an odor coming from her mouth. Could it be wet fowl pox? If not, what could it be. Is there anything we can do for her? She’s our sweetest chicken and is almost 5 years old.

It's probably canker (trichomonosis) . Is there a foul smell?
