Hello I am wondering how long everyone keeps their young birds on chick starter and what they are feeding up to 6 months. I have the BC Marans and they are medium to large birds I guess. The breeder I bought mine from however has birds on the large size so I think mine will be big birds. Anyway, they were developing sooo fast in the first 8 weeks. And when I ran out of starter the guy in feed store said put them on all purpose crumbles, they only need the starter for the first 6 weeks. About 3 or 4 weeks later I felt like they needed more protein, so I started mixing game bird/turkey grower crumbles in with the all purpose. I also add hen scratch and sunflower to the mix. But it sounds like some people keep them on starter until they are ready to lay. Should I just go back to the starter? Or maybe the Purina start and grow? They are around 15 weeks now. Your learned advice is greatly appreciated!
