How would I go about transitioning my week old chicks from regular starter/grower to a medicated starter/grower? I have mentioned in other threads that these chicks were a literal surprise gift from a neighbor. And she had bought me a bag of feed also. So I really didn't put much thought into what they were being fed. I am still not 100% sure if I am going to switch to medicated. But if I choose to I would like to know the best way to transition the chicks. Is it harmful to switch their feed from unmedicated to medicated?
