I just extended Duma and shorty's outdoor pen from 2.5'x3' to 3'x9'. I was wondering if this would be considered enough room for them until they are big enough to have run of the back yard? or should i be planning to make room for something larger in the future? Shorty is a yearling and is 266g and Duma is just under a year and is 109g. I almost feel bad for them come winter time. next i am going to have to find a way to make their indoor enclosure bigger!
