Need a little help settling a debate: better to move the chickens onto gravel/rock under the porch or tuck the tractor in next to a tall stone wall to the north of the tractor (where we understand prevailing winds will come from). The tractor is an a-frame - base is 4 x 8. One of us is worried the tractor will blow over, the other is worried about the chickens on stone (standard 1"ish rocks - not great for barefoot walking for humans). We're right outside Philly so going to get hit pretty hard later today. Any reasons to stay off rocks for a couple days or avoid high winds? Thanks in advance and hoping everyone else hit by this storm weathers it safely.
