Poo is very common when you soak a snake. It just seems to lubricate the poo or maybe there's something primordial. I don't know, but it happens many times. You may also see water coming from the snake's mouth too. this also is normal.
As far as the blood, was there much of it? Was it bright red or more dull? I don't have an answer for you, but it it continues a visit to the vet would be recommended.
Good Luck!
