i mean...technically you can. Feed questions always bring up a ton of answers.
so i'll just give you what i PERSONALLY think. others will be different
I don't use medicated feed, that doesn't mean you can't, some folk on here can only get medicated feed so thats what they use. Some folk say it causes infertility, some folk that use medicated feed say they have non of these issues.
I just stick to non-medicated. As far as the chick feed aspect, you might want to look for something with a little higher protein content. 24%+ is recommended. Ideally you want a 30% feed, but not all of us can find it. If you are lucky enough to have a purina supplier around you talk to them and get them to get the Purina Gamebird Startena, its...IN MY MIND...the best feed out there.
if you don't have a purina dealer, then just get the highest non-medicated feed you can find, crumbles of course.
once again this is My opinion on medicated v. non-medicated feed.
