My boy Donald needs help. He is a 4 yr old Pekin. I believe he has bumblefoot and I am treating it with Epsom salt soaks and using iodine on the wounds with compression wraps. Both legs are swollen. I believe he may have a niacin deficiency after reading many posts I believe due to season and less free ranging. I do have B12 tabs on hands 1000 mcg per tab but I don't understand how much to give him he is about 10 lbs. He shows signs of weakness and stress. I have him inside away from the others for now. I am bringing in Angel because she has been having a difficult time walking with her on leg. She is only 3 months old. I thought the wrap on her leg for a week fixed the issue because she was doing amazing but she is back to limping again so Epson salt baths and wraps for her. Am I doing enough for Donald and is there anything else I can do for him? Do you think I can put these two together or should they be separate but able to see each other? I am thankful for the other ducks if it weren't for them I would not have found him he got stuck in the mud and his buddy Mr. Dufus stayed with him until we came for them while the rest sounded the alarm. I feel horrible because I work from home but couldn't get there for over an hour due to my work. It was the only place in their pen that the camera doesn't show. Looks like I'm getting another camera. Any help would be appreciated thank you
