#1 Mike is not the first person to have BP's in captivity. There is no need for further experiments about multiple housing, it has all been done before.
#2 You have 3 ball pythons (as per your sig) how can you make an assumption that they will OK living together. I do believe that the snake on top was the dominant one. By you stating that "they swapped" tells me that they were in a struggle for domination.
#3 Good luck letting them rest 1/2 a day after eating before handling. I'm sure that's gonna work out great in the long run.
