Hi all! I've read a lot of conflicting information on when to switch chicks from a medicated starter to an unmedicated starter/grower. Our chickens are currently 11 weeks old, and have been on Manna Pro's medicated starter from the beginning. We put them in their outdoor coop/run at 4 weeks (so they've been outside on medicated feed for about 7 weeks). So far they've been very healthy and happy. We've just switched them over to a non-medicated, organic feed--Nature's Best Starter/Grower--and I'm having anxiety about whether this might have been to soon. We're currently mixing it in with their medicated feed until it's gone, which will only be a few days. Is that too quick a transition? Should I get another bag of medicated feed, or purchase Corid to use as a preventative? Thank you in advance for your help!
