Let me see if I can describe our quarantine barn, that is used for older horses now.
It is an addition to our old quonset barn, with six 14’ x 14’ stalls and still under roof a 14’ overhang, in a straight line, except we have only formatted three and left for now the other three as a large run-in from the pasture, with equally wide pen in front of them.
Those three have outside runs.
We can open the middle, center wall, wall to the fourth stall, it swings and so have a larger run equivalent to four stalls long.
We have kept in there as a herd up to five geldings that get along without any trouble, mostly three or four.
All our stalls are portable panels, easy to move around, store what we don’t use.
That one middle stall wall hangs from that metal column very solidly, is easy to swing either way and fasten back.
We can close the middle wall and have three stalls with individual runs.
Here is a picture with the middle wall closed but the overhang clear to the end, not closed for individual runs, there were no horses there, we had power washed and were repainting.
The other picture with two horses that were new, so still kept separated:
