I feel like most new chicken owners are like me; we think that medicated chicken feed is a must. After a lot of research though I've found that it is only recommended for large commercial flocks. My tiny flock of three chickens doesn't need it, so I've switched to non-medicated.
Having said that, I'm happy to have started our girls with this food. They are thriving and healthy at four months old after using this for a couple of months. We've had zero health issues, and it's clear that they have been fattening up. They are sweet and friendly and have free-ranged in addition to using this feed.
