I know that Vagrans have one of the most diverse, if not the most diverse diets of all garters, and I've read many times that they will eat small birds. Is this practicle at all? Any cheap birds that are easy to aquire (not looknig for chicken/turkey meat or chicks)? Would it be safe to get a small sparrow or will it be filled with parasites and have lice? Don't kill me for asking this bird lovers! Just trying to mix up my snakes diet as much as possible.
