This morning two of my chickens came out of the coop very slowly and did not want to eat. They both stood around closing their eyes and one of them drank a bunch of water. I have brought them both inside and offered them water and scrambled eggs, but neither seems interested. I checked their crops, the one who drank a lot of water (Grey Wind) feels like a water balloon, the other (Rosie) feels like a bag of grain. Grey Wind has gone to the bathroom twice, both watery, the first was yellow and white, the second brown and green. Rosie hasn't gone since I've been watching. Grey Wind just passed an egg with no shell too. (Pictured below) I have no idea what is going on. It seems like their symptoms could be several things and I'm not sure if they are even suffering from the same thing. Please help!
