I am beginning to worry that I may have a rooster. the brownish one (Gabby) has been quite aggressive, pecking at the children and me. She is also much more standoff-ish than the black and white one. (Molly). Also, Gabby's comb is much redder than Molly's. I know these pictures aren't great. my girls are getting very attached, though and we can't have a rooster in our city. Thanks for your help!
