I am new to keeping chickens and have learned a great deal in reading on BYC. We have our first illness in the flock. We have 6 hens and one rooster. Our 9 month old brown leghorn was missing 3 days ago when the girls were out to free range. We found her under a bush and not moving. She let us pick her up (not typical) and has remained lethargic. She mostly stands or lays but can walk if we try to get her to. She has not been eating and rarely drinks. We did quarantine her right away and the other girls seem fine. Her droppings are very watery and slimy. They are a mixture of black and white, I do not see any blood. Her eyes look good and clear, her vent is clear, we do not see any signs of injury on her body. She has not laid an egg for at least 3 days but I do not feel any lumps and she does not seem to be in pain. We did some reading on BYC and have given her some Corid just this evening via a dropper. We are trying to feed her peanut butter but she is just not interested in eating. We would appreciate any advice that you have! Her name is Kernel.
