I am a Buckeye owner as well.That's why we ordered them this year...we need help with mice, and they are supposed to be excellent foragers and hunters! Our chicks at 6 weeks are super curious and friendly too, and have gorgeous plumage. Although when picked up, there's a few who are very vocal about their displeasure!
Also, I love the idea that they were "Made in America", and that they have a small comb, our poor Buff Orp roo got frostbit last year (MN), and we were looking for something with less exposure. The American Livestock Conservation Society has a cool article on Buckeyes
Have fun with those chicks!
