Chicken newbie here. I have 6 chickens and they all seem healthy and happy (of course I've only had them a week, so I know that can change). But now I am looking at how to prepare my coup for winter. I live in GA (USA) so it doesn't get super cold here, but I was still considering doing "heavy bedding" (is that what it is called when you just put new wood chips on the old to increase the heat in the coup?) Anyway, I am asking if I should put a layer of DE in the coup and in the nesting boxes under the shavings and straw. Also, should I worm the chickens? If so, with what product? Should I dust the chickens with sevin dust to prevent mites and lice? I don't seem to have any problems yet and I want to prevent the icky stuff if possible!! Thanks for any advice!!!
