We rescued a duckling from my Aunt's ranch about a month ago, he or she (no sign of gender yet, about 6 weeks old). Duckley was about to become hawk food because his left foot is sort of backwards and cannot support any weight. It seemed to get better for awhile when he was littler but now that he's had a growth spurt we can really see that the foot is not working at all. We've built an outdoor pen with a pond that we've made accessible with bark and small pebbles to make getting around as easy as possible. My concern is whether we need to intervene or just let the foot develop as it is going to on it's own. We do not have a ton of resources to invest in this venture but are willing to keep him/her for the long haul since release may not be an option with this disability. Any ideas on whether or not we need to do anything or just leave it be?
