About a week ago I noticed that one of my ducks was limping. When I picked him up I saw that he was completely missing his very back claw. When I checked on him today I noticed that another claw on the same foot was cracked at the top and had turned a dark color. His claws are suppose to be white. I just happened to glance at the other foot and he was missing a claw on that foot! What's going on?? I checked on all my other ducks and they have all of their claws... I'm about to buy booties for him until his claws grow back... What can I put on the wounds to keep infection away? What should I do?
