We have been having constant rain here in Northern California--the kind with high winds. Even though my 2 pens have a roof, they are completely sopping wet. The hay and alfalfa bales we have in there have turned moldy, and I'm afraid I have exposed my chickens to it. Even worse, I have contracted pneumonia, and my doctor suspects there is an allergy component to it. Mold?? I'm looking into a solution whereby I can put up panels of plexiglas during the winter in the runs, or at least on the sides that are exposed to high winds. Has anybody ever constructed something like this? Any other ideas??
