I'll try the vitamin complex. She's otherwise 'healthy'. No mites, lumps, bumps, crop feels normal.
She's also on chick starter for her main diet. She sometimes gets into the other chickens layer pellets but 90% of her diet is the starter
Can you please get some photos of her legs, joints and feet/bottom of feet too?I picked her up around 6 weeks ago and within 3 days of having her she was unable to walk without dragging her feet. I'm just so confused because as you can see, she walks normal sometimes.
You've had her for 6 weeks? Is it possible to get a fecal float to rule out worms and/or Coccidiosis?
Was she added to an existing flock? Any chance she's been injured or stepped on?
