I have two game banties that we are still unsure of their age. We're guessing that they're over 6 weeks old though because they're fully feathered and have been for quite some time. They are now outside in the coop and run. While they do eat their chick starter, I often see them eating the layer crumbles that I have out there for my other girls. Will that hurt them? Oh, and I find my older girls eating the chick starter. One last question... What do I feed the rooster when he gets older?
