Please help. This morning I went to feed my ducks and chickens and found my duck Hopes face was swollen both sides, however worse on the left side. About a month ago I had posted about her she had a sore leg thought it was bumble foot but couldn’t find any injuries. Then figured she had injured it. Started giving her vitamins in her water daily and she had been doing much better. Her limp was almost totally gone. And she was seeming to be more active. Just fed them last night and she was fine. Now this morning her face is swollen. What can I do. I really don’t have access to a vet. I do have a few feeds stores near mean may be able to get something there.
