He he he, funny post
OK... Ahem. I guess the first question is WHY is it muddy?
My chicken shed is super muddy right now *sigh sniff* even though it does sit on elevated ground. My problem is that when the snow starts to melt, the ground is still frozen, the building is painted a dark red, so the snow against the walls melts first and the only place the water can go is into the building the floor of which is way below the mountain of snow all around. I am thinking that this summer.... When the snow finally melts and the ground thaws (you know, about a month from now *massive crying*) I am going to dig a trench around the base of the shed and put in a skirt of roof paper and wire, so the rodents don't chew holes through the roofing paper, and I am thinking maybe maybe maybe that might work.
OK, I guess you can ignore the above, it was just to illustrate that there are many reasons that you might have a muddy run problem.
If you just have a dirt run that is mud only when it rains (so no standing water) you can just add lots of sand, make sure you edge your run so the sand doesn't run off.
So what are talking but? Mud? Sanding water? Erosion? And what is causing the problem?
