We've had so much rain recently that the ground around our chickens pen/run has become very soggy and muddy. We've been moving them around from spot to spot to keep them on fresh grassy dryer ground. In the areas where their pen has been there are chicken droppings and spilled food. With all the moisture in the ground these areas are actually getting moldy! I'm afraid that the chickens will range in these areas when they are out. Is there anything safe to do that will kill the moldiness but not harm the chickens? I'm hoping the sun will come out eventually and dry the area up - but what to do in the meantime!?
