We've had a couple of rainy days lately and this morning I noticed mold growing near the edges of the coop. The coop is rainproof for the most part, but the water still splashes in from outside a bit. We removed (hopefully) all the mold that we found today, but is there a way to keep the grossness from sprouting up again in the future? Also, what sort of health impact does mold have on chickens, particularly chicks from a month to two months old? Thanks!
