We used to have the guinea pig and the rabbit together, but the rabbit kept escaping so we left it to do its thing. It now really thinks its a chicken, and while not being very tame, has a wonderful and very free life. The problem is I feel very sorry for the Guinea and I think I should open the pen and let it also roam free. My son is devastated at the thought of it running away. My thinking is that if we always keep food and water in its pen with the door open it will always come back to it 'home' and there's no reason for it to go very far away. The bunny has never tried to go further than the chickens do and they are completely free range. Does anyone think this is tru or will he just keep runnning and never come back?
