Please help me save my hen! I've noticed that one of my leghorn hens has been acting strange, more lethargic and subdued than usual. The other day my mother noticed that she was 'vomiting' a clear liquid and asked me to investigate. I approached and immediately noticed that she was acting strange; she was huddled into herself sitting outside next to the coop door and not engaging with her flock. I picked her up, which normally she wouldn't let me do, and immediately began expelling a clear liquid from her mouth. I held her until she finished and decided to separate her from the flock just in case and put her in a wire pen with fresh hay, water with cider vinegar and some mealworms. She seemed to perk back up and I returned her the next day. However, it's been two days and my mom noticed that she wasn't doing well again. She was lethargic again and saw her poop a greenish slimy poop and then expelled fluid from her mouth again, only this time it was a brownish-yellow liquid. I again held her until she seemed to finish and she's eaten and drank a little but she's still very lethargic. This time I also noticed that her rear area was dirtier than normal and was covered in poop. I want to clean her off but I'm hesitant to get her wet as it's below freezing right now where I'm at. I've asked fellow neighbors who have chickens and they're unsure, they think she might have a blocked vent, but I'm unsure how to remedy that, plus I'm afraid to wash her since it's so cold. Please, please someone help me, I've done so much research and it's sounds like it could be a dozen different things from asistes to sour crop to some kind of bacterial infection. I'm not sure what to do or what she needs! If anyone could give any insight or advice I would be extremely grateful! If you also know a good poultry vet or a vet that would see chickens in the Broomfield, CO area or somewhere nearby please let me know! I love my hens and I want to save her!
