I am looking to build a cool room that is able to hold atleast 3, but no more than 4 heifers. I have been able to gather some valuable info from other post on SP about types of units and insulation ideas, but one factor that nobody has mentioned is the size. My family is new to showing cattle and I want to make sure I build a cool room that is big enough to house what I need it too, but not too big that I have a problem maintaining the temp. So if possible I would like some ideas on the dimensions that I need to be looking at constructing. I appreciate any advice on this topic. Thank you.
