Rooster with foul sweeth breath!!

[Babis]

Hi!
My 2 year old rooster has had a sicklu sweet smelling breath for several weeks and I dont know what to do :,,(. I live in Sweden and vets dont treat pet-chickens here. My local vet reccomend that i put him down!!! He eats and drinks ok but his feathers are quite dirty and hes lost some weight. All antifungal meds and antibiotocs are on prescription here so I cant try and treat him myself. Please can anybody help me or give me advice on what to do!!!! Kind regards

Welcome to BYC!

How does his crop feel he may have sour crop.

Hello masterofClucker!
Thank you for welcoming me!
His crop feels quite small,even in the evening. Its nighttime here so he is asleep now but earlier i could feel some grit and food there. Not much liquid. He sneeses a bit too.

Coryza can give a foul breath smell and Sneezing .

Yes so I heard . But Coryza seems to make the bird sick quite quick? My rooster is quite fine. He eats and drinks and takes care of his hens. Its just the weightloss and smell . Could it be a fungal infection?
