We built a small enclosure about 6 feet in diameter so I can take the snakes out for awhile. I have only been taking one ball out at a time. I have to watch them while they are out since it is not escape proof. All three are females, all about the same size. Do you think I could put all three outside togethor at once? They could stay out a lot longer since I wouldn't have to divide the time to give them all a chance. I never leave them when they are out. Thanks in advance for your help.
