Hello. New member to BYC, thank you for accepting me! We started off with 7 chickens, 6 hens and one rooster about five years ago. Not sure if their actual age because they were given to us full grown. Over the years we’ve lost some due to predators or unknown causes. We are now down to one hen (Pumpkin) and our rooster (Mister). Over the last winter they became infested with lice/mites which we treated (several times now) with elector psp. Mister, during this time started have spasm like seizures. They start out with him lowering his head, spreading his wings then jerking his feet and head, at times very aggressively. Often ending up on his back. He’s losing his feathers, has a rash that I’ve been treating with neosporin and vetericyn spray. After hours of research it seems to me like it’s a vitamin b12 deficiency. He’s been given nutri- drench and rooster booster, scrambled eggs, beef liver, dark salad greens. I’ve been keeping him on the porch in a box with a heat lamp due to his feathers loss. Last night was the first night that I didn’t find him on his back every time I checked on him. He’s still having the fits throughout the day though. Is he improving or am I kidding myself? He also has a bumblefoot which I’m treating to treat but it’s difficult to soak him because of his spasms. My husband said we should have put him down weeks ago but I hate the thought of it being something that I just haven’t tried. Any advice would be appreciated. Also, he has a great appetite, drinking lots of water and poops seem to be normal. I just don’t feel like he’s dying, I feel like I’m failing him 
I have a video but don’t know how to upload it.
