I have now isolated Rueben in a large cage in the barn away from the other chickens. I have treated his foot with some (believe it or not) Preparation H to reduce the swelling. Tomorrow I will head to Langley to get some antibiotics and proper treatment cream for him. I have done some research on this condition which, in 20+ years of poultry keeping I've never seen, although I HAVE heard of it in parrots. Poor Rueben. Hopefully he will be back in action soon. When we put his food and water in his cage tonight, he seemed very thirsty. Good thing we noticed him up at the far end (it's over 100 feet long and the weeds are very long right now). So, he has nice clean water and fresh food now, and a safe, clean place to sleep tonight. It's always a bit stressful treating the outside animals because we don't see them all the time like the inside animals. Rueben is used to being handled and fussed over, however, and he's a very good patient, thank goodness. When I picked him up at the SPCA, the girls there had grown very attached to him.
I have to be very careful in treating Bumblefoot. The staph or other bacteria that cause the abscess can infect humans. Best to wear gloves in case of any open sores or nicks on your hands. It also can be transmitted to the inside birds.
Hopefully Rueben will be back to his old self in no time. I'll keep you updated!
