Thank you everyone for the kind responses and suggestions, unfortunately after a very emotional day of thinking I have decided to have her put down as I noticed her body getting worse, the last straw that convinced me was that her wing was stuck in an uncomfortable position and she didn't even bother moving it, she also made no attempt to even sit herself back upright, only to kick her legs and squawk, she seemed to be in pain or fear just attempting to get off her side.
I had suspected she was beginning to develop more paralysis throughout her body due to her using her head/neck to regain balance.
She had not began suffering as I kept her warm and well fed, but she had definately began to physically deteriorate, going from being able to walk on two legs, to barely able to stand on one, to sitting, to not even being able to sit herself up.
I can only hope that her final days were pleasant, I feel terrible putting her down when i can't tell if shes in pain but I hate even more prolonging her life if shes only going to continue to deteriorate to the point of suffering.
My flock at the moment is only 4 other birds who sleep directly connected to each other, so I don't think I will have a necropsy performed as if it were contagious, it almost certainly has already spread, I can only hope it wasn't.
I am heartbroken and wanted to avoid this possibility at all costs but seeing her worsen significantly over the course of 8 days left me with very little hope that she would recover. I truly hope I made the right decision.
Thanks again all, love this website and I just wish this had a happier outcome.
