Getting close to the day we take home our first chicks. We're getting 4 of them...couple questions: 1. How much starter feed will we need (total) for them? Wondering what size bag to buy. 2. Thoughts on medicated vs. not starter feed? I know that's a huge topic and my inclination is to go medicated since it's our first go-round, but we're going to try and raise them as organically as possible. Any advice from somone who tries to straddle this fence line would be appreciated. Thanks!
