Deworming free range chickens , can it be effective ?

Hey chicken lovers.

Wondering what do you think based on your experience ?

We don't have control of what our chickens eat , we cannot be safe and sure our yard is 100% clean to avoid reinfection.

deworming can keep them clean for about 3 weeks.

Periodic worming helps keep your birds from developing massive infestations if you indeed have a parasite problem.
