I have an easter egger that is on the thin side. She is showing no sign of sickness other than being thin compared to her flock mates. She seems to only want to free range and stay reserved with her layer feed. I am wondering if she is just being picky with her food or do you think there is something else going on? When she free ranges she stuffs her crop. The past few days it has been wet and rainy and staying in doors she doesn't seem to eat as much.
