Do I need a wormer? Wazine?

[tone3822]

Hello. The person I bought the chickens from told me to use this wazine but the warning says not to use on chickens laying eggs for human consumption.

Do I need a wormer?

I don't worm my chickens unless they have it.The worms can build up immunity.You can PM @casportpony she knows a lot about worming chickens.
