Yeah I'm keeping my boys separate when I'm not home, I have plenty of corrals so they can be side by side in different corrals. The younger bird Ed is much larger than my older bird El and he's very excitable and crazy. What I've noticed is Ed will walk up to El, stare at him, and El will get upset and start running and then Ed goes nuts chasing him, not kicking or biting but still El gets scared and runs into the barn and hides or runs to me for hugging, so I don't know whats up. If I'm out there with them they walk around peacefully, they sit together eat together sit in my lap together, but as soon as i go in the house I hear the running and have to go break it up, and Ed stops it as soon as I'm in sight, Ed apparently has the right name aka eddie haskel lol.
