The only way to properly gauge crop function is to check it first thing in the morning before she eats/drinks.They do have access to grit. I haven't personally seen her use it, but then again I'm not there all day.
In the morning, her crop is soft and mushy. It is possible that she has eaten stuff since I'm catching her after she's been let out. (My mom keeps forgetting to check her crop before she opens the coop door.) I definitely saw her peck at something on the ground this morning.
Did not check her crop this afternoon because she was enjoying some spaghetti squash. This evening she had a very hard, densely packed crop, about the size of an orange.
I'm hoping she's eating when I'm not home but I'd feel better if I saw her.
When you do that let us know what it feels like.
