The decision to use medicated feed vs non medicated feed is a personal one, there are pro's and con's with each. Many people prefer not to medicate unless it's necessary and don't want it in the feed. Some worry about causing thiamine deficiency in the chicks since amprolium mimics thiamine. There is also discussion on whether using low 'preventative' doses may contribute to medication resistant forms of coccidia. Honestly, you should do what you are comfortable with. If I had lots of trouble with coccidiosis and was losing a lot of birds (some strains are more virulent than others) then I might consider using it. But I've found that by introducing them early to the natural microbes and keeping things reasonably clean I've been able to hugely reduce my incidence, so prefer to just treat when necessary. When I started out I pretty much had annual outbreaks, now I've not had to treat in I think about 8 years. If you have coccidia in your environment, and it's very common, then at some point they will be exposed. It really is everywhere, it can be brought in on clothing, shoes, wild birds, etc. Trying to be totally biosecure with a backyard flock is nearly impossible.
Having healthy birds in a healthy environment and treating as early as possible are the best tools for outbreaks.
There are many, many articles on line regarding using medicated feed or non medicated. I've never used it. You really have to decide based on your own beliefs, comfort level, and what keeps your flock healthy.
This is a good article on coccidiosis, treatments and prevention. It gets a bit in the weeds but the section "Conventional Coccidiosis Control Strategies" is fairly easy to get through.
