Hey, I'm getting ready to de-worm my chickens for the first time, starting with some wazine 17. I've done a fair bit of reading on here about it but I was wondering if anyone had any information or advice about keeping the entire farm worm free. I have a dozen chickens, three sheep and nine barn cats (that came with the property). They all mingle. If the cats have worms, and I assume they do, then is it true that everyone has the same? I'm guessing some parasites are universal and others species-specific. The cats were de-wormed at the TNR center this spring, the sheep were treated about the same time. The chickens have never been treated and are going on a year old so it's time for them. Can you give cats wazine? It says it's not labeled for such but it doesn't say that you can't. But they poop everywhere in the barn, especially with all the hay laying around and the chickens routinely scratch in the hay for oats and seeds. Then the chickens poop there too and of course the sheep. Does anyone have a set schedule and tested method for treating the whole farm? Are there special concerns in regards to parasites that I should know about when having animals mingle like they do?
