This is Mrs. Doubtfire (now aka "Fluffy"). (S)he was my "free" mystery chick from Murray McMurray. This is the quietest bird of the entire bunch, and whenever (s)he does chirp, it's very different sound from all of the others. (S)he is also very large and was very, very slow to get any feathers. I have a Black Cochin Roo who is the biggest chick besides this one (though he is definitely the man of the chicken house). I don't mind if she turns out to be a "he", but I'm a little concerned because (s)he isn't as much of a "lap chicken" as we have groomed our known rooster to be, so I want to be sure to start bugging him more so that I don't have to worry about the grandchildren around them. (S)he is 7 weeks old in the main pics, and the 1 week old pic she is with the other chick I don't know the breed of (they are both splash with a slate bluish hue).
