I recently wormed my hens as you all described in the blog on worming. I use Safeguard in the water. Finishing up on second round and waiting 2 weeks. The question is do I need to do anything about the soil?? The vet I took my hen to for diagnosis mainly or only saw exotic birds. But she said 3 feet of soil in pen needed to be removed and replaced with top soil? I'm not sure that is even possible here. And I've never seen any posts about soil.
