Hello,
Please help. My BO hen, Rapunzel (age 4.5 years) has had these lesions in her mouth for about a year now. I took her to the vet in January and had a swab/culture ran on a sample of it, but the results came back inconclusive. The vet gave me a run of fluconazole, since I suspected it was thrush. The meds didn't make any difference. The hen was still acting fine, so I did not cull her or separate her. Fast forward to August 18th, we notice an EE hen (Anna) sneezing and shaking her head, flinging clear fluids. I look at her mouth and she has the same lesions. I posted on her and canker is mentioned, so check all the other hens. I find one more with a teeny lesion on one side (Pocahontas, my other EE). I separate the three hens from the other nine and begin treatment. I started with 25mg/kg of metronidazole (Fish-Zole) daily, but after a few days, I upped it to 50mg/kg. A few days ago I upped it again to 250mg per hen. All doses have been divided into three servings. I mix a crushed pill with water and give it orally. I removed all lesions from their mouths (I had to scrap or pull them out in teeny pieces with a hemostat tool). All lesions plus more are back in just two days.
From all my googling, it seems yellowish lesions are either thrush (yeast), wet pox (virus), or canker (protozoa). Well, it didn't respond to fluconazole (yeast) and seems to be getting worse with metronidazole (this is day 13 totally, but day 4 of the max dose of 250mg/hen daily), and I don't think it can be wet pox for an entire year since it was supposed to clear in a matter of weeks on its own.
I keep a fairly clean coop and the 12 hens have a 700 sq ft run. The only thing I can think it that it is yeast from mold pellets (twice I've gotten moldy feed from our local hardware store, and didn't see the mold until after they had eaten some... I no longer buy food from there!). It could be canker from the morning doves (no pigeons around here), but it's not at all responding to metronidazole.
The hen who started sneezing three weeks ago is no longer shaking her head or sneezing, but the lesions re-grew and are far more than before. Also the hen without any symptoms but with the single lesion, now has a mouth full.
I will cull these sweet birds (they are all 4.5 years old) if I have to, but I'd love to figure out how to cure them if it really is just yeast overgrowth (and that makes sense since the antibiotic is making it worse). The three girls are still separate from the others. Both pens have had a five day run on copper sulfate and ACV in their water as well. I have enough metronidazole to complete day 14/day 5 of the max dose of 250/hen daily, but I'm not sure if I should. May I should try another antifungal since it doesn't appear to be canker after all.
Please advise. Thank you!

Here is a comparison from Aug 27th (the day I started treating the hens with metronidazole) to today (top four pics are Aug 27th and bottom three pics are from this morning).
I did complete remove the lesions a few days ago (again) and they've regrown worse).
Thoughts? I'm afraid I'll have to cull these sweet girls if I can't cure them. They have lost weight and the BO is having trouble breathing. Thank you for your advice/help.

I removed the lesions multiple days in a row and they kept regrowing.
I took a sample from two hens and viewed each under our microscope (all three magnifications) and found nothing that moved (no flagellated protozoa), but I did see bubbles (in the tissue, not only in the spit), so I do believe it was a yeast.
(The results from the lab said the same. Inconclusive, but they believed it was a type of yeast.)
I don't know why it didn't respond to antifungals, but it did get worse on antibiotics/anti protozoan meds. Their breathing was audible this morning and I know we made the right decision...
With heavy hearts, we culled these hens today. We cuddled them and thanked them one last time and then put them down.
(Updating & leaving these posts just in case it will help someone in the future.)
 
I'm sorry to hear about your hens :(
It sounds like you have treated for everything that most would have.
Do you plan on sending a body to your state lab to see if you can get a diagnosis?
 
Thank you, Wyorp Rock.
We chose not to send in a body for necropsy. Our state vet lab cost $75 per bird plus $50 in overnight cold pack shipping (or a 5 hour drive). I have heard of too many inconclusive results to spend that much money on maybe finding out something. If it shows up in more hens, I will cull immediately and if a third outbreak happens, I may just cull all birds and wait six months and then start over with new chicks again. I really do think it was yeast overgrowth from the moldy pellets I picked out of a "new" bag of feed last year. I suppose the other hens have stronger immune systems as they never caught whatever sneeze/respiratory issue I brought here via the auction hen in 2016. The three I put down today not only caught the bacteria or virus from the auction hen in 2016, but had "flares" or bouts of sneezing again (once each year for a week or so) since then. No other hen (I have 8 others) ever have recurring respiratory issues.
I realize I should probably cull the remaining 8 and start over since there are so many unknowns, but they have zero symptoms of anything being wrong, as far as I can tell. I'm going to weigh them all tomorrow and maybe worm them (I've never wormed any chickens). Plus I already have 13 chicks (one month old) and don't want to cull them as well. All seem like healthy chicks (aside from cocci that I'm treating with corid) and the rare sneeze when eating from the Polish and one silkie chick.
I guess if the Polish and Silkie don't stop sneezing, I will cull them as well. Ugh. So hard.
 
Thanks, Tonyroo.
I'm the only chicken owner in my area. My friends have chickens about 5 miles away and they are fine. I don't think it is contagious since it's been hanging out in Rapunzel for over a year... whatever it is. (But yeast overgrowth in a hen with a weaker immune system just makes sense, I think.)
I'm hoping that is all over now since we put them down.
 
I do now. I hadn't ever thought of looking for a manufacturing/milling date before all this. And I don't buy from that hardware store any longer. It happened twice that I got slightly moldy feed.
Thank you.
