So my coop is mostly open, I'd say the whole top 1/3 of 3 sides becuase in my area in california it doesn't often get below 30 even at night but summers are over 100 for sometimes 2 full months. Except that I have a tarp over the roof and 2 sides right now due to the roof leaking and I should have built the north and south sides up higher for wind protection. The floor is dirt, ideally it would be cement but that will have to wait till we can buy land. So my issue the coop is 95% dry especially since we added the tarp over the roof. But I'm worried becuase the past few times I've cleaned the coop when moving the feed and water the ground is damp and has a white mold or fungus growing under. We built some wooden block platforms to set the feed and water in to help raise them up and to level them better. But I'm still finding this mold under the blocks (at least it's not on top). I'm seeing 1 or 2 issuses. Of course the water is a plastic container and if not level will leak, adding to the water in the soil. But the feed is 3 feet from the water so I'm assuming that either moisture is just collecting under the block or coming up through the soil. So 1 is a simple white mold dangerous? Especially since it's contained under the block and they can't scratch or peck at it? I'm assuming any mold would be better to not be there at all. And 2 what can I do to help eliminate this issue? I need to keep the water in the coop at least over night becuase we have had a few freezing nights and would prefer to have a water both in and out incase I can't let them out at first light like normal especially during summer. Would it be best to just lay some pine shaving on the ground for extra moisure control? Is there another product that might work? Should I even worry about something contained and hiding under a block (as long as it isn't exposed or touching the feed and water)?
