I get my chicks next week!! As excited as i am I'm also worried that ill screw up. I plan on working in leaves from the yard into their litter so they're exposed to the germs in our run and consequently their future run. I don't want hens that every time they get a runny nose i shove medicine down their throats. I'm getting non-medicated organic chick crumbles is there anything i can add to their water (no chemicals!!)?? I remember reading somewhere i could add garlic or ACV to the water. Any advice from the as close to nature as possible chicken people?
