I am looking into building a outdoor enclosure for my 2 beardies. They do not get along so I will have to build two enclosures. I am thinking about a 4x4 area and cut it in half. They will be 2x4 each. I am also thinking of going 2~3 feet high. The enclosure will be covered with Chicken wire to keep out predators. There will be plenty of shade and plenty of basking areas. I am not limited on space. I may make each 4x4 but an wondering if that will be too big. Any thoughts or suggestions? I live in Phoenix AZ. Day temps will get up to 115 and nights will drop to mid 60s.
