Thank you for your post and sorry to hear of the difficulties with your Grey. Two of our members who cannot access the discussion forum but wanted to assist, had the following suggestions:
“A bird sitting head-down, eyes closed is not a good circumstance. She states she has medication, but doesn’t say what. I would hope this hypocalcemic condition and liver condition were diagnosed by an avian veterinarian. If the diagnosis is correct this bird should have been given an injection of calcium and maybe more to follow and should most likely be on lactulose for the liver condition and a modified diet.”
“I’d create a soothing, calm environment where if the parrots wants to sleep, she does so without unnecessary interruption and in peace. If the parrot wants such ministrations and if this feel natural to both, holding her on a towel on the lap might be good. Whether or not there’s physical contact, settle the thoughts into calm, healing and soothing rhythms. When the parrot is awake, offer her some room-temperature water in a familiar bowl. If she allows, moisten her feet with water, and her face. Keep her as comfortable and hydrated as possible. Model calm healing comfort to her. Give her assurances that help is on the way.”
I hope this is of some help.
