My chickens crop is not hard, but big and full of water... all she seems to want to do is to drink, and ate a bit yesterday... she has also lost alot of feathers and the other girls were picking on her and trying to fight her or something. Now she is inside and in her own little cage. Her droppings are all water. Any ideas? I have just given her water with vitamins and electrolytes to see if that helps. Any other suggestions?
