Oh good. I'll keep this stuff around then. Hopefully I won't need it.That Amtyl is pretty good stuff, safe for chickens. I'd check the expiration date to be sure it's still okay since you don't know how you came by it. I'd try the VetRX first for a couple of days, and if it gets worse, that would be a good choice. You can also order the VetRX online, but it'd sure be easier if you could buy it off the shelf. I've never seen it sold at TSC, but my Atwoods store usually always has it in stock. I buy 3 bottles at a time. I don't go thru it that fast, but I like to have it on hand. If anything goes wrong for me, it's usually after hours, during a holiday or a major snow storm where you can't get out. Always. LOL! So I think ahead and buy things a little at a time and keep a medicine cabinet full of meds for the birds, horses, dogs, etc.. My vet knows me well and will keep me supplied in injectible meds too, so I don't have to go driving clear into town.
OH and BTW, I do use pigeon products on my birds because it's often better than what you can find labeled for 'chickens'.

I think we also have some sort of a feed out in the barn that's supposed to be medicated. Recommended for respiratory diseases and such. I'll have to go find the bag and see what this stuff is really for.
