Honestly I think she looks pretty good based off of the pictures. My BO was all fluffy like that when she was a chick, fluffier than my other breeds. I would guess that she may be too warm if the pasty butt keeps coming back. Maybe if you move the light up a bit, maybe like 6 in. further from the brooder, she will still get the warmth but won't be too hot. She sure is cute.
