My OEGBs have always been good free range chickens, although they are a very docile breed. I love having a few in my flock, especially a rooster to guard the flock. They are alert little birds and very smart. They seem to really pay attention to danger and take care of their girls. I've had the OEGBs for about 5 years now, chickens for about 20-25. I will probabaly always have some OEGBs in my flock, especially a free-ranging flock, from now on.
I really like the Sicilian Buttercups, too. Not as wild as the Hamburgs and Egyptian Fayoumis but still with good foraging/flighty instincts. Same with the Silver Leghorns, although they aren't as curious or personable. My Buttercup and Banty hens are always underfoot, hoping I'll find them some bugs in the garden.
