Remodeling

These two fillies are in a corral made of heavy steel panels. Panels heavy enough that I can't lift them by myself. It is a sturdy pen.

Last night they turned the corral into a squeeze pen. From the inside. I tried to pull out one of the corners with the quad, without success. I will have to take it apart to get it square again. Fortunately I was able to find the problem with my electric fencing, so the girls are sequestered in the surrounding field.

Why would they rearrange their space? I have no idea. I don't even know how they did it. Silly horses.
