I have 6-7 week old Barred Rocks (4 hens, 2 roosters) and almost 3 week old Black Copper Marans. The Marans are much more aggressive that the BR's every were at this point. It is warm enough that they could move outside soon although they are not fully feathered yet. I was planning on keeping them until they are mostly feathered and then move them outside. It will be nice to get the barnyard smell out of my dining room! How do I go about doing this? I was planning to let them outside with the big kids to see how they do but how will I know that they older chickens won't torment them when I'm not watching?
