Noticed that lately some of my anconas have been limping. Not the same duck and it doesnt even last all day. They are eating same diet as always, layer pellets, veggie scraps, and whatever they find in the yard. My wife wonders if they are getting stung by bees? Does this sound like a possibility? Their yard has quite a bit of clover in it and there are tons of honey bees. At first I thought no way that their feet are too tough but since it doesnt last very long I am starting to think she might be right. Any other possibilities?
