Sorry to burst your bubble, but I don't think its a burm, or maybe you mean 6 yards. Even a male burm would be at minimum of 10 to 12 feet at a couple of years old.

It sounds like this snake is either not a burm, or severely malnourished. There is a slim, very very slim possibility that you may have a dwarf burm, but I dont think there is any dwarf albino burms out there, especially one that is several years old.

Post a pic, even if it is a cell phone pic.
