like a lot of you have said, my mules (2) have access to the barn at all times but will usually only go in it to escape the heat/flies in the summer. I realize it must not bother them but i hate to see them standing out in the rain,ice,snow. I was thinking of just building one wall as a windbreak and putting a roof over the lee side, leaving 3 sides open so they could see in all directions. Has anybody tried anything like this or will they still stand out in the weather? I know, I know,they really dont NEED it. It is really only for my peace of mind. ha ha
