My prized sweetheart, Elvis (see avatar), seems to have completely lost the ability to walk/stand. He will drink and struggles with the strength to eat, but tries. We noticed a couple of days ago that he would flap his wings when walking up the ramp to his box.... I noticed since then that he lays around a lot under the bushes. Today, he is toppling over on his head and side. He is super thin around the breast bone. No obvious signs of injury, eyes are clear, nose is clear, breaths well. ???? Two days ago I put vitamins and electrolytes in his water. What else can I do?
