Is there a way that you can kill cecal worms in the ground?. Is there a pesticide? I have such a small place I have 18 chickens 3 of them are free raging. I started on raising turkeys and have lost all of them to black head disease the last one passed away tonight. ARRRRRRRGH I get attached to them to just loose them I am tired of getting my heart broken when one passes away. The chickens I have all seems to be resistant to the disease but I got 2 week old silkies afraid of loosing them to the dreadful disease. There is not animal hospitals around here that works with farm animal so I am left at trying to treat the birds by myself. I bought a bag of medicated feed called Strike 3 which has hygromycin from tractor supply I am not sure if I have purchased the right thing or not. I hear about fishzole but I do not know anything about this kind of medications or how to use it. First of all what do I do first?
