I live in the Santa Cruz mountains of Central California and we get a ton of rain each year. I've built a lovely coop and run (8 x 12 ft enclosure). It has sand in it, but I'm wondering if I should provide a dust bath area for them. At present, while the weather is good, I let them out to free range in their chicken yard...and they have access to lots of fresh dirt to 'bathe' in. Anyone have any ideas? Thanks!!
