I've seen a lot of topics and pictures of chickens taking dust baths and I'm beginning to get a little worried. Our property is mostly a pile of rocks. Where there aren't rocks it's heavy vegetation and we get a lot of rain. Kodiak is actually considered a northern tropical climate (we've had over 10 inches of rain in May alone!) I don't have any dust piles or open dirt that the girls can take dust baths in. Can I make one? They'll be in coop with a covered run and I haven't yet decided if I'm going to put a sub-floor in or leave it on the bare earth (that's my preference but worried about predators). They'll be able to roam the yard when we're home but there still aren't many areas with good, dry, dusty soil for them to bathe in. Any ideas?
