I'd really like to put my 11 7-week-old Light Brahmas and Buff Orpingtons together with our 3 13-week-old Black Copper Marans. They are currently in the same coop with a near invisible netting dividing them and appear to be accustomed to seeing each other; they've been next to each other like that for two weeks now. They even sleep close to each other on occasion. My main reason for wanting to integrate them before the 7-week olds are older/larger is that it's so hot here already (heat index yesterday: 105 degrees... ugh) that I want them all to be able to go outside where it is cooler. There is one BCM rooster and one Light Brahma rooster, just fyi. I'm must wondering if... even though the BCMs are older and larger, will they be intimidated at all by being outnumbered by so much? I do have a fan blowing in the well-ventilated, shaded coop and lots of water and everyone seems okay, but outside it so much nicer and the ground is much cooler than the pine shavings inside. Plus I'm sure the young'uns are plain jealous; I feel bad for them being under lock and key. However, I don't want anyone getting hurt; they are all such sweetie-pies. Any sage advice?
