I got my girls last week, 4 pbr @ 10-12 wks old......I was @ the nearest feed store and she said a couple things that confused me a bit. She said the girls can't have leftover/people food, gives liver disease????? Then said my girls shouldnt ever need grit???? I gave them a halfcup of oatmeal with some crumble once earlier in the week, which they really liked, lol. So, am I feeding stuff I shouldnt be? I bought crumble feed from "Chickens Galore", when we picked up the girls. Thanks!
