How about cornish game?

I don't believe you have to dub them. They're quite the opposite of modern games though; they're short stubby little creatures. They grow a little slower too, but meat is excellent and they can be very docile if you handle them a good bit. I have a trio and though at 5 months they're still much tinier than my 5 month old silkie, who really isn't that big to begin with since he/she is a bantam too lol. Does your daughter like to show them?
