Yesterday I started my flock on Corid because they're losing weight. While at the farm store I also picked up VetRx. The stuff sounds pretty amazing for "colds, roup, scaly legs, eye worm", etc. It's also super simple to use according to directions. Has anyone every come across this stuff and used it? A few of my birds sound congested and I'd like to hear if anyone else has tried it. It can be found doing a Google search for VetRx Poultry Remedy. Thanks.
