Large lump on pullets back

[darkroo]

Oh have a seven month old pullet with a very large bump on her back. It's just off center towards her right rear and covering about one third of her back. It seems to be getting bigger every day. I've gone through her feathers and haven't found any kind of wound or opening on it. She didn't make any kind of indication that she was in pain while I was looking her over. The skin over it looks normal. I'm not sure what to do about it. Any help would be appreciated. You can see how large it is in the pictures her sister is lower and shows how much flatter her back is.

Probably just deformity and nothing to worry about, is it swelling and seems a bother to her? BTW, you should name her, 'Quasimodo'.

Well her name is Roxy, when I first notice it that's what's was thinking. But it seems to be growing now.
