She could be someone's only snake.
I have a friend who wants one boa. Just one.
I'd give her to him, on the understanding that she had IBD and that should be his only snake -- and that at some point, she may fall ill.
She's in a 4 part rack by herself (it wasn't in use before I acquired her). Assuming she tests positive, will time and cleaning with a bleach solution make it safe to use again?
