I've read a lot of similar threads, but am feeling overwhelmed. I recently started work at a poultry farm and after about a week, I found out that the chickens needed to be treated because they had a respiratory issue. OK, fine. About a week or so later, my rooster started acting funny...lethargic, following the others, but keeping to himself a bit, fluffing up his feathers, and occasionally sneezing. I contacted our local Cornell Extension Agricultural Office who told me to go to Tractor Store and tell them the symptoms and they'd have something I could add to the water, etc and there were a few other directions to help him. He said it was exactly what a vet would give me. Of course TS had no idea what I was talking about. They had Tylan-50 (I think that's what it was called), but it was an injectable and for cows/pigs and couldn't give any advice about it. Now I'm hearing a few other sneezes from my flock (though everyone else still *looks* ok - not like the lethargic rooster). What should I do? The office I spoke to did suggest a vet, but if she's just going to give me the same thing that TS actually has, I'd rather do that first. Any ideas on how best to proceed? I am tempted to call the office back or to speak to the vet, but it irks me to spend hundreds of dollars on a vet visit if TS actually has what I want, but just don't know it. And any advice on preventing this in the future (as I now work at a poultry farm)? I have since bought separate shoes, but is there anything else I should do?
