I think you'll find Doms are sweet birds. We got ours b/c our daughter liked the looks of a friend's Barred Rock. (However, I disliked how they pecked at fingers & wanted something a little more unique.) A Dominique was the answer. I'm always impressed at the intelligence of our Dom. She's also a very people friendly bird that fits right in with the flock.
After years of pining and research, I finally got some Dominique chicks. They're feed store hatchery quality, so I'm sure they'll be far from the SOP, but I want to get a feel for the breed before I start actually breeding to the standard. I'm only 25, so I'm not a homeowner and have limited resources. But I'm working my way to hopefully being able to help preserve the breed in a few years!
