I have a hen, about 11 months old, that has been standoffish to the others for a few days. I didn’t think that much of it becasue she’s the most timid of the flock. Last night she didn’t go in the coop for bedtime so I went out and got her. Felt her chest and didn’t feel and hard lump. Put her in the coop for bed and saw that she was almost acting like she had hiccups, but also turning her head and puffing her neck quite a bit. This morning she didn’t seem interested when the food came out. Brought her in and offered her bread soaked in olive oil- she didn’t want it. Mixed some scratch mix with olive oil and she ate that, but now has twice thrown up a slimy clear liquid. Any ideas what’s wrong? She hasn’t laid since it got quite cold- several weeks. The rest of the flock seems healthy and is acting normal. Liquid next to her in the box is the throw up. She also just had a very runny poop.
