Ringneck snake

[Marley]

Ok, so I came across a very nice ringneck snake today while working in the yard. She? was curled up underneath a largish rock that was in an old fencerow I was cleaning up. Looks like numerous old injuries - bites? - along her length. She is the largest one I've ever come across, probably 16" long. Do they do well in captivity or would it be best to release her again? If she is a candidate for living in the house does someone have a link to a good care sheet for her? Thanks!
