If you had worded it better, it would have been easier to understand. You didn’t say she was a house chicken temporarily... you said she is a house chicken and can’t go out until well. See where some confusion might come through?And you just ASSSUMED she NEVER GOES OUT. I even SAID she "can't go out until well"
Anywho, it sounds like it has neurological issues - either that or it really wants out. You haven’t provided any pictures, so no one can really help to confirm
fowl pox / eye injury.
