What did you feed them? I believe they eat worms and slugs, but I wouldn't know where to get them in winter. My son wanted to keep some, but I opted to get him a corn snake instead. This also helped teach him that wild animals are supposed to stay in the wild.
Yes, the 2 ringneck snakes I kept from the wild have led to the collapse of the ringneck snake population. I feel so guilty about it! Just like the 3 deer I shot in PA last year led to the collapse of the deer population. I feel so guilty about it!
