I've looked at Aquasol and it's too expensive but more importantly it doesnt mention that it treats capillary worms. Capillary worms are more prevalent and dangerous than cecal worms.That would be great to live closer, Jim. I did worm them all by myself several times when I had 70 birds. Then I tried the wormout gel, and now that I am down to 20 birds, it is much easier to dose with Valbazen. Now I just have to wait until dark when I go into their coop, and take them off the roost. You would love to see me with my red lamp on grabbing chickens, LOL.
The new fenbendazole product, SafeGuard Aquasol for use in the water would be easy to use, if it were not so darn expensive. Here is a link:

I see you like "reverse chicken math" like me! Hahaha. Even 25 birds was really too many for me. I was comfortable with 10 to 18 birds. I have 10 now and that's it.
