This is a 6mo Black Sex Link, not yet laying. She is one of 8 birds in my flock. Symptoms include: Totally lethargic Standing up all day in one spot like a statue, sleeping, eyes closed Fluffed up feathers especially around neck / chest with head tucked in Will let anyone walk right up to her and touch her and pick her up, very unusual Tried to put her beak into a water bowl to get her to drink, uncertain if she is eating or drinking Yellow, runny poo I don't really know exactly what I am feeling for, but best I can tell her crop does not feel impacted and neither does it seem she has an impacted egg (if it is even possible I would be able to feel it). As of right now, all of the other birds appear to be healthy and behaving normally. No indication of any insects or of any worms in poo. Thoughts?
