I've been feeding my chicks non medicated feed all their lives so far. 4 of my chicks are 14 weeks (?) and 2 are almost 4 weeks. I haven't had any sicknesses or anything, but I'm going to get more chick starter/grower today and I was wondering if I should get medicated this time. Is it really NEEDED or should I just feed what I normally feed? I'm just wondering if it would help at all. I wouldn't buy medicated again after the bag was gone, I'd just get non medicated.
