I have an EE that was acting a little wonky the other day, clumsy. Today it is obvious there is something wrong. Breed: EE--ish Age: 12-13 weeks Symptoms: Off-balance, no "spring" in step, puffed out--- as though cold, clumsy, falls when she tries to jump/hop. Appetite: Good, saw her eating and drinking fine less than 10 minutes ago. Energy: Seems lethargic, but still wants to explore with the flock. Was too easy to catch Crop: Normal sized. Fills up at the end of the day. Skin: No mites, no pecks, no pulled feathers. Color and sheen are good. Respitory: No wheezing, sneezing, coughing, rattles. No discharge from eyes, nose, or vent. Other: She likes to sleep under the BO. I have seen the Bo knock her off the roost. Possible head bonking from falling off the roost? The rest of the flock is healthy and rambunctous. There have been no introductions to the flock except for my own hatched eggs--- All the chickens ate 16 weeks or younger. This EE was in a batch of 12 bought as day-olds. I have not been around any other chickens or to the feed store in a while.
