I’m going to do the full prazi treatment just to be safe. I ordered medication to treat velvet as well so that I have it on hand if needed. It won’t come in until Saturday tho. In a pinch I’ll run to the store and get some copper treatment.Yes. Been there. The problem is that these diseases are coming at you much quicker than normal with almost zero time to react. You did what you could under the circumstances. Sounds like your Cardinal had perhaps some flukes, velvet and developed a rather nasty bacterial infection in a very short time.
