Hey I have a 24x24 metal building on my place. It has 2 8ft entry ways on both sides (breeze way) I was wondering if I put in 4 8x12 stalls would those be big enough? I know the rule of thumb is 100sf per horse. But I don't know anybody that has 8x12 stalls 8x12=96sf. These would just be used in harsh weather or illness. I live in Oklahoma, so we have freaky weather. Please give me some feedback.
