Hi, I just went out to close the coop door and I noticed that my NN looked "husky". Just where her naked neck ends and her feathers start on her chest, is a stretched sack about the size of a small orange! It is a bit squishy. I do not think it was there yesterday. The neighbor girl came by today and gave the hens raw rice. (????!!) Could that have caused this? Is it impacted crop? Please send any and all advice - I love this little hen, Coco Chanel! Thanks!
