She seemed to be limping and when she walks rocks heavily from side to side. I have thoroughly checked for Bumblefoot and any feet/wing injuries and nothing! She's always kinda walked that way but lately it seems difficult and she's been a bit immobile, though still has a healthy appetite and otherwise acts like her normal self! No puffed up feathers, diet is the same, what gives?? 10 week old Pekin/Mallard. Thanks for any insight!
