We spontaneously bought 2 Muscovy ducks a couple of weeks ago at a market. We have already fallen in love with them as they are the cutest, most affectionate birds we have ever had. They started off in a cage with straw at night and have been allowed to roam free during the day when we are home, and we gradually introduced them to the chooks and they have now being sleeping in there the past few nights without any dramas. Today when I let them out I noticed 'Bob' is limping a little, but hard to know if one foot is sore or both. One foot looks a little swollen and both are much warmer to touch than his mate 'Pip's feet. No obvious injury apart from a small round circle on top of one foot near the middle toe. Not sure if he had stepped on something or maybe one of the chooks pecked it, but there isn't an opened would top or bottom.
