My chickens have bugs. I've tried about everything. This summer I started with DE. That didn't work. I tried the Carefree Enzymes both spraying the coop and the birds. That didn't work. Then I got poultry dust from the feed store and I've used 3/4 of the bottle of that on the birds and the coop and this morning when I checked I still have bugs. What did I do to actually get rid of these pests? I have 60 chickens and winter is just around the corner. I've even put wood ashes in their dusting areas. I'm not sure what else to try. Our winters are too cold for bugs to pulling my birdies down, plus they are so awful and crawly! I need advice!
