Our coop has about 6 inches of straw in it and today we found about 5 chickens dug into it and acting really silly. Our only thought is that they were trying to dust themselves and the snow outside wasnt going to work. So...can we put wood ashes in their 'pit' or is that bad for them? I'm sure they need to dust in something and putting something outside isnt an otion. Maybe DE and ashes? Would ashes be bad for them if it got moist on them? Wouldnt it irritate their skin? Ashes is the only thing I've heard of using. Anybody got any ideas?
