where can I buy Valbazen. I have never wormed my chickens, and there 4 years old.
is this the best stuff to use?
I dont even know if my flock has worms?

how much do I give them?

I bought mine at my local chain type feed store.

The dose is 1/2 cc for standard chickens and 1/4 cc for smaller/bantams. I think it's great stuff because it kills all types of worms.
