my young boa went blue 3 weeks ago and hasn't shed yet. i keep her just like i keep the others and they usually shed a week after they go blue. i never heard of anything like this. if you can give my any information on something like this and an suggestions on what to do i would apprciate it. the only sort of herp vet in my country , there are no real ones, found nothing wrong with her and doesn't know what to do. she still eats . any help?
