Hi, I have two 5-day old ducklings that I just picked up yesterday. One of the ducklings has been limping and after taking a closer look, his right foot appears to be swollen. The limping duckling seems to be in very high spirits despite the limp and is just as energetic (playing, eating, drinking) as the other duckling. I am wondering if anyone has had a similar experience as this and could offer any advice? Could this be a possible injury or maybe even an infection? And does anyone have any recommendations on what I should do?
