I want to use the deep litter method for bedding and then eventually transfer it to my compost bin or garden But I also want to make a dust bath and maybe leave it outside the coop. I heard this is good for mites etc. This includes using garden lime. But I heard this was not good to use I if using the deep litter method. Would this be a problem if I left the dust bath outside? Or would they bring it inside on their feathers?
