Worming Chickens in Hot Weather

[vonchick]

After seeing a roundworm this morning, I realize I need to worm my flock. My question is, can I use a product mixed in their water, Wazine in hot weather? It's in the high 90s here with a heat index over 100, and the birds are drinking a lot more water than normal. Is there a wormer I could mix with their food?

Any advice would be appreciated.

Ive actually heard a lot of folks say that if you sprinkle chewing tobacco in their food it will act as a dewormer..
