They definitely look like partridgey birds...Splash partridge maybe? I've heard and seen partridge come out of BBS pens, so the white "sport" could have been hiding the partridge.
I really like #1 - I have been looking really hard for a similarly colored girl. I take it since their your daughters none are for sale - LOL (I can dream) I have a "Splash Partridge" boy who is gorgeous.
You guessed it...she's my daughter's favorite.
Do you have a pic of your partridge boy? I would love to see him!
