Review: Excellent stuff! - Works well for feminizing flower. Very impressed!
Review: If you have Zebra Finches... - ...just order this stuff. Our two Zebra Finches seemed to have eye issues shortly after we got them. We were so heartbroken...with these teeny little birds, the nearest vet to us who even knew anything about treating them was a couple of hours away. Poking around online revealed mites as a possible culprit, and colloidal silver as a possible remedy. It really did seem to help. They were fine for a long time, but then after the pandemic really hit they both started acting fussy and itchy again. I found this seller on desertcart. The first order cleared up the eye issues right away, so we slacked off on using it with our birds. We won't make that mistake again. One of them developed a frankly horrifying-looking wound near his eye from the scratching. We started using this stuff on them again, and I don't know how it works, but it works. It's just CRAZY how it works. His wound completely healed up! We add just a couple of drops in their water dishes each day, and spray them with it at least a couple of times a day. They actually really love getting sprayed. Y'all, these Zebra Finches are close to ten years old, which is ANCIENT for them. And they're doing great! I'll keep using this stuff on them!
