I have a partridge rock a little over two months, she has a massive crop. I have massaged it and you can feel the grit, and crumbles, scratch. It feels like a hackie sack. She acts fine is the first one to the feeder when I fill it drinks normal. Poops normal. Should I be worried. I noticed this about two days ago. This morning it looked smaller before I fed so I think its emptying. Should I separate her and measure out her food for a couple of days? Any advice is welcome. Thank you.
