I would like opinions/ experiences on medicated (Amprolium only) chick starter vs plain chick starter. I've googled & read lots of posts, but am still undecided. Brief background: I raised 10 chicks last spring on medicated to POL, lost 0, they did great & currently free-range w/ yogurt, BOSS,sprouts, etc for treats & layer pellets. I've read posts about building natural immunity by allowing exposure to the bad stuff they will encounter in their environment & since this birds will free-range, that makes sense too. (I had even bookmarked an excellent post that I of course I can't find.) I'm sure there is lots of 'stuff' in the soil now since there have been 22 chickens + wild birds on it for almost a year. This new batch is 35 days old give or take; I have been feeding medicated starter, weekly yogurt, & just added a dish of dirt to the brooder, but was wondering when/ if to switch to plain starter. Just to clarify, I'm asking medicated chick starter vs non-med. chick starter, not switching to some other feed. Thanks in advance for sharing your wealth of knowledge.
