That's great news! I truely hope that is what it is!
Thanks kari_dawn, and Dawg. You're right; I realize that I was the one who suggested it might be coryza, but that's because the only info I found online pointed to that symptom of smelly discharge. But I said early on that he showed no other symptoms and seemed happy and healthy. There were a few people who were sympathetic to the dilemma of trying to figure out what it was for sure or who kindly explained why culling might be the most responsible option for the sake of others in my flock (and the flock's of friends, etc.), and I understood that -- begrudgingly.
But when I found an alternative explanation for what might be going on, and it's a fairly innocuous yeast/fungal infection, and the symptoms better match what I see on my bird, I would kind of assume that people would agree that a watch and wait situation might be warranted instead of informing me that culling is the ONLY option, and I would be irresponsible if I didn't cull the birds ASAP, really offended me. I couldn't help but infer a kind of holier-than-thou glee about culling, and the suggestion that I should try to "out" the breeder (whom I consider a friend of sorts) seemed mean-spirited at best.
I may very well post a pic today so that folks can see the bird has no swelling and doesn't appear sick in any way or that he doesn't even have the discharge, maybe people will feel more comfortable about considering the sour crop option. Either way, it doesn't matter. I have an appointment with the vet at 10:15am. I'll share the results at that point.
I truly appreciate others' input, but not when people suggest I'm not doing the "right" thing -- I've done nothing but try to do the right thing for these birds since the moment I opened the shipping box on Thursday. I love my animals and
all animals for that matter (except snakes).
