I used my own version of "imprinting" with all my foals with great success. I think it can be harmful if not done correctly and consistently and should only be done with foals that will be under the care of humans for most of their early life. Attempts at imprinting, when not done by someone with experience, can be very dangerous. A frightened foal tends to jump towards its mother or handler not away. I would never recommend a novice try this on their own.
And PS.....Never...ever...feed a foal by hand!
