I was able to get the hens outside yesterday and close their pop door in order to shopvac the dust that was building on ledges and in corners. Oh and the spider webs! Now I can enter winter a little better with the dust down. A tip when you're buying shavings- if the bale feels extra-heavy it is probably the end of a run and contains mostly sawdust. Switch any of those for the light ones and you will get less dust from the bedding! (Sawdust sticks to eggs)
