My poor Pekin has been gradually going lame. She'd walk just fine one day then the next be unable to get up, then walk again the next day. But now it's been 3 days of no walking. Nothing wrong with her feet or legs. No swelling or heat in them, kicks fine when I pick her up but can't sustain her own weight. She struggles to get uptight from laying down. Before she'd just struggle to get upright but once she was she'd walk fine. About 10 weeks old. Tried niacin supplements for a few weeks with no improvement. Does anyone have any other ideas or ways I can save her or help her heal? I've had her in her pool a lot hoping she'd heal up if she at least swam but still doesn't move much there, either.
