Is it canker, wet pox or candidiasis ? Wrong cure by the vet ?

[Mrs Wick]

My Cream Legbar hen had light yellow stuff in the mouth. The vet diagnosed canker (trichomonosis) and she had surgery (removal of an olive-size plaque in the mouth) + Alazol antibiotics.
She was fine and I let her back in the garden.
3 days later, same thing !
I gave her antibiotics.
No more effect.

Was it not canker but wet pox ? Or candidiasis ?

Every day I remove some stuff so she can eat (she eats only our canned corn), but from time to time I remove this kind of big stuff : blood + hard pieces that look like beak bone.

An idea ?

You need to sterilize all the feeders and waters daily. Do small birds get in?
Does she get any real food?

Where are you located in the world?

How long was she treated with Alazol?

Is there a rotten bad odor from the plaques you are removing?

Are any of those plaques way down in her throat?

Canker can be very hard to treat, there is no cure, just symptom management. You may want to ask your vet for another treatment like Metronidazole or if you can find it, use Acidified Copper Sulfate to see if that makes a difference.
Canker is spread through water/food, so I would not allow her to share water and feed stations with other poultry.

@dawg53 may have other suggestions/thoughts.

Canker is contagious to other birds. It would be best to cull the infected hen and bury her deep away from your coop or incinerate her.
If you're not going to cull her, keep her permanently separated from the rest of your flock and practice strict biosecurity.

She has been isolated since I found she was ill.
I gave her Alazol at least 20 days, it seems a lot to me (0.2 ml, her weight is/was 1kg).
I'm not really sure it is canker, as the plaque is growing.

Can your vet give you a different medication to try?
