Today I discovered wriggling grains of rice on an otherwise normal looking poo, so obviously we have worms. (So much for being a "Natural Chicken"
) We live in a rural area with the closest feed store an hour away. I have some round wormer for cats that is 250 mg piperazine per 5 ml. Can I use that on my chickens, at what rate, and what is the shelf-life of said wormer? (I've had it for about year or two.) Oh, and what kind of worms are the wriggling grains of rice? Are they round worms or tape worm segments?
