I am in the process of putting up 6x6 and 6x12 pens out of dog panels in a 12x24 covered horse pen. I have 3 6x6 and a 6x12, soon to add another 6x12 and 6x6 with a few more panels. I put panels on top too, just to keep them from pen hopping. Kinda crowded, but I think it is better than having them out in the rain this winter. We have not had much, but I'm sure it will come soon enough. I didn't care for the stinky slick pens with just this last rain we had. fooch! I would rather them stacked a little tight but dry in my "Project" than sprawled out in my "Shantytown" I had working before... lol. Dry and wind protected trumps wet and windblown any day in my book. They seem to like their new digs and are not stressing or fighting. I will try to post pics soon.
