I'm new with chickens and don't know if I'm posting the right place or not. I recently noticed a couple of my chickens with a lump on the front of them, which I determined to be their crops. I can feel the feed in them. I have never noticed this before, so wondered if this is normal and I've just missed it, or what. One is my very favorite hen, Sweet Pea, and I hold her a lot. She also seems to be very skinny, but acts like she feels fine. Any help would be appreciated!
