Hi! My little mutt duck started limping on her right leg about 2 days ago. I checked her feet and legs and everything looked normal. She was active, eating, and otherwise normal. I thought maybe the drake sprained her hip or leg. Today, she is still limping. I checked her and now she has a swollen "heal". There was a hard spot in the middle of the softer area and I removed scab and found a little (3/8") thorn. I removed the thorn, expecting the soft area to drain, but it didn't. The thorn was already walled off from the swelling. She's still eating well, active, alert. So, should I a) lance and drain swelling, apply a'biotics, bandage, give injection of a'biotics and keep her inside b) nothing c) something in between a & b? Thanks! The victim There looks like there is still something (little black dot) in the middle of the wound in this picture, but there is nothing actually there.
