What's wrong with this chick?

Sorry for the poor photography, it's hard to use an iPhone and hold a wiggly chick.

The chick is nearly six weeks old. Doesn't act weird or anything but see the photos. There's a bump on the front of the breast (crop?) and the underside has no feathers at all. It is one of three Ameracaunas. The other two do not have the same problem.

I'm new to chicks so I don't know if the lump is the crop or not but it's soft and pliable.

It looks like the crop to me. Either way, don't panic if she's bald in a few places until you investigate. I had a tiny, scrawny chick who had so little feathers that you could almost see straight through her skin, but she grew up to be biggest, fattest, healthiest hen. On the other hand, maybe the other chicks are pecking her but I doubt it. Pecking is more common among adults and they would have drawn blood by now.
