I need some help. In my seven years with chickens, I have never had mites - lice, yes, but not mites, and even that was many years ago, before I started using DE everywhere. Now that I know what I have, I've dusted every bird, and added dust to their bathing holes. I discovered the mites when I brought my big cochin hen into the house on Friday because she was acting ill. I looked at her vent, but didn't see anything, but as she's a dark partridge, that may have hindered me. Yesterday I felt like my skin was crawling, and when I looked, there they were! I could barely see them, even under the brightest light! No wonder I couldn't see them on my bird. I ran out today and loaded up on Sevin Dust, and dusted all the birds. Took the bird in my room outside, dusted and changed her cage and her, left my clothes outside, and took a shower. Later, I was wiping up the table around her cage and a few minutes later the bugs are back on me again! Do I have to bomb my room now? I also noticed when I reached in the cage to check the one bird that she still has living mites on her, because they were on my hand and my shirt. How long does it take for this to work? Will these things crawl all over my house? The bird is too ill to be outside in the cold - what do I do??
