I know people say this a lot but "I have mites!!!!" My questions: 1. How can I get rid of them a naturally. (I've tried D.E and it was a no-go) 2. How could they get mites in the first place 3. How can I prevent mites in the future? Random Info: I have 7 black Australorps hens and no rooster. I use plastic nesting boxes and straw bedding in coop and nesting boxes. My girls are losing feathers and not laying. I don't have any perches because my chickens don't roost at night. If you could give me advice to get them to roost that would be awesome.
