I have a female peking duck (Millie) that I have had for 6 months now. I had two, but we lost one New Year's Eve when the neighbor's dogs attacked them. Since then Millie has had a slight limp with her right leg, but otherwise got around normal and continued with her duck business. I've noticed her walking seem a little more challenging the past couple weeks. This week however, her walking has drastically changed and she's using her wings to balance before she falls down. I checked her right foot and she has a lump on her middle toe? but her foot isn't swollen and the lump isn't warm. Now she's barely walking at all. She leaves her pen during the day just to sit right outside of it and forage. She's eating and drinking, but barely makes it a couple steps before she falls. She swims fine and bathes herself whenever I put her in her big pool. I was thinking it was bumble foot but wasn't sure since the foot isn't swollen and the lump isn't warm. Any ideas,suggestions, feedback is greatly appreciated.
