It was recommended that I use this on my chickens that had bumblefoot. It seems to have helped them along. I also had another unknown illness spreading through the flocks that this may have helped with as well. Since my chickens will eat from my hands I was able to treat them without separating from the others because they enjoyed their flake "treats".
I was skeptical at first but thought I didn't have anything to loose since I had a chicken with severe bumblefoot (not able to walk at all). I figured it was worth a try before I had to put her down. I fed large amounts of the medicated fish food by mixing with a liquid (I used the juice from canned cat food) to make a sticky "dough" out of the flakes. I then fed her these fish food "dough" balls 2x per day for a full 14 days. She gobbled the food up readily and within a few weeks has made a full recovery.
Absolutely fabulous product, would purchase again, and again.
I am using this for treating bumblefoot for a rooster, in conjunction with home surgery. It seems to help, although since it's a severe case, I am using it long term. He does not like to eat it alone, so I am crumbling and mixing with things like chickenfeed, cooked oatmeal. Chopped oatmeal. I have used it in the past, and some chickens will eat it by itself.
It may not work with that feeding regime, because the concentration of medication depends on the animal eating nothing else. If it doesn't eat enough of this flake, the amount of medication consumed will be too little.
