I rescued two elderly boars that had come with a 2 by 3 witch as you guys know isn't a suitible enough size for two pigs. Me and my mom want my dad to build an outdoor shed that equals about a 2 by 4 or a 2 by 5. We also want the shed to have a little gated area in the grass where they can lounge around and do guinea pig things, since they love going out in the grass. But because my weather can be so unpredictable I don't know if switching the guinea pigs in the summer to outside or switching them inside when it would get colder would stress them out.
