I recently acquired a young chick with wry neck and I've been trying to think of other ways to get the vitamins into her (she's just far too stressed when I separate her to eat anything I give her with the vitamins in it so aside from the polyvisol that I drop on her beak - I was thinking of putting a supplement in they're feed. (ultimately only a selenium OD could be harmful right? ). Has anyone ever used a horse supplement? for instance: http://www.opentip.com/Home-Garden/Selenium-Horse-Cattle-Care-p-515484.html or http://www.opentip.com/Home-Garden/Vitamin-Selen-Crumbles-p-1227775.html I know I would have to downsize the amount quite a bit. My vet suggested feeding tetracycline (so I could just put this in the food or water also right?) Then All I need to do is figure out how to feed Vitamin B... (( I was also thinking about getting liquid Vit.E - because cutting the gel caps is getting very old very quickly - walgreens claims that they have an E-oil that is save to administer to people orally)) suggestions? what has everyone else used?
