Belly Burn on Baby ball?

[DVirginiana]

How big should their enclosure be in measurements? The baby will have it's own always. The two adult balls that were gifted to her have been in the same enclosure together for 11 years+. Female is 13yo and a little over 5 ft long and male is 11yo and is about 4.5 ft long. Their previous owner was power feeding them several large mice vs. rats. We have started them on rats and they are doing okay. Zooy is aware they like smaller spaces but an experienced ball owner told us their enclosure is much too small and needs to be nearly double the size it is now to house them. Currently it is 4ft. wide x 3 ft tall and 15" deep (looks like a big fish tank with a wood back. Plexi glass sides with the front side removable for easy cleaning. Top is very sturdy with heavy rabbit cage wire enclosed by wood. The top locks down in place with hook locks. The previous owner originally put the heat pad directly in their enclosure and the male ended up with a belly burn several years ago. The burn is healed, but the scarring from it is visible in a small area. We know that is unacceptable and she is very cautious. With these snakes having been together for the length of time we are talking should we keep them together? They have never breed. Their previous owner had little to no humidity in their enclosure and they had consistently bad sheds. Since we got them we have had a good shed from the male. I will try and get some pictures to post in the next day or so. Any advice regarding enclosure would be fantastic. We have begun a larger enclosure, but could pare it down if need be.

Some people can keep BPs together for years and years with no problem, and some people end up with injuries or rarely even snakes eating one another. IMO cohabiting is a technique better left to experienced keepers; it won't bother the snakes to be separated.
Someone with experience cohabiting BPs can give you better info on the pros and cons, but I think you may be better off separating them for now.

Also, they may not look as pretty as a tank, but rubbermaid tubs that latch can make good enclosures especially if you need something quick and inexpensive to house the two normals separately.
