I've been thinking about starting a small feeder mouse colony and there's a question I want to ask the established breeders here. Do you handle & tame your feeder mice from birth or do you not bother with that at all? If you do put the time and effort into taming them, why do you do so? Personally, I'm trying not to get attached to those buggers so I think minimal contact is best, not to mention it prevents the spread of diseases and all that. Thoughts?
