How do you identify crop problems? Don't think she has any... She eats fills her crop and sometime later it's empty, fills it again and so on and so forward. They all free range, they are never locked up (except at night), they'll eat grass, clover, apples that fall from the trees, crickets, spiders, in general insects, I've seen some of them even eat frogs and mice, talked with people that have game birds also and they say it's normal (saw one of our chickens killing and eating a snake once too).
