Bloods are notorious for bad sheds even if it is not their fault. They need large water dishes and as they get to big for reasonable sized water dishes they may need to soak in the bath tub 2 or more times a week or more during shed. They need a humidity above 70% on regular days and 80% or better when shedding. In the wild they live near bodies of water they can enter and soak in regularly, but in captivity it is hard to get a water dish that is big enough for a 5'+ long snake that is thick to soak in. The humidity tends to be an issue due to the fact that if you keep a room at that humidity anything in the room will start to grow mold. (Already had to gut my old snake room because of it.) Now the snake room has Green board and mold resistant paint. Also all the electrical outlets have a little extra waterproofing.
