Update on Ghost- It's been 10 days, she eats and drinks on her own- but needs to take her time- looks like she has to focus on the food, still moves equally, eyes are clear, little comb is bright- I really love that it's also called Star Gazing, since thats the perfect description of what she does. I took her out of the Chicken ICU in the garage and put her in the grass and snow. She walked around normally, pecked at the grass and was a general happy chicken, though still with the goofy head maneuvers on occasion.
I did a trial with putting her back with her flock, she was super excited to get back in there, she heard them clucking and called to them. The other ladies and our rooster were less than welcoming. I let them be for a little, since it's been over a week that she's been out, they were brutal, and she ran back to me. : ( I was unsure if this was normal re-pecking order behavior or the girls being mean to the different chicken, so I tried it again. Again the rooster and a couple hens came after her. The majority didn't even care that she was back.
I took her out again and let her loose on the outside of the enclosure, she happily snacked on my frozen herbs... and tried to figure out how to get back to her flock.
When she is walking her head is mostly normal, it seems when she gets stress her head goes wonky.
I'm thinking maybe its a combo of something different / you've been gone for a while.... I'm going to try the 'hello box' we used for new bird introductions and we'll see.... there's plenty of feeders / waterers so I don't think she'll have issues getting to the food, but I am concerned about her freezing at night not being with the others huddled in the coop.
Thanks for all your replies- hopefully she can re-integrate with the flock....
