So we decided to exchange our Pebbles (who as it turns out was a Fred) because he was picking on my other two. We got one that looks the same except we're fairly sure that this one is a girl (lots of feathers and nearly no comb). She's so much smaller (about a third the size) and was getting pretty trampled by the 23 others in my neighbor's brooder that I just had to "rescue" her. She is so sweet! My other two liked her instantly and everybody is happy. I'll have to post a picture so I can get opinions if this one is actually a girl or if I'm just really bad at telling the difference.
