Crooked boobed chicken?

[willowandthyme]

I'm not sure if this is the right place to ask but it doesn't really fit anywhere lol.
I have a chicken (columbian rock X from Frey's) and she seems to have a very large breast on the one side. When I picked her up she feels very meaty on the right side of her chest but almost hollow on the other. My experience with chickens is somewhat limited as I grew up with barred rocks but I don't think this is normal. She walks fine, lays fine etc and I'm not planning on breeding or anything but I'm curious. Some of the others seems a little lopsided but nothing like her. Should I let the hatchery know?
Thanks!

Also should their breasts be very pronounced? I always thought they should be smooth out front

Are you sure it's not a full crop that your are noticing?

I didn't even know what a crop was until just a minute ago but no its definitely not that. Before I let them out in the morning she's crooked and there's nothing but her feed to eat and their last meal is around 2pm.
