Thanks for letting us know! Like you said, glad it's not something you'll be dealing with in the rest of the flock. Still hate that for your sweet girl though 😔
Are there any poisonous plants around their area she could have gotten? Screws, nuts, bolts she could have ingested?
The first guess with waterfowl is always toxin, or they ate something they shouldn't have. Hope that's not the case with your girl! She sounds like a tough one!
