ok! is this also something that would cause her to fall over?
Worms can rob a bird of nutrients and make them weak. Whether or not they are contributing to her decline is hard to know. So many things affect chickens.I went to get her to bring her in and get her cleaned up, she ran about two steps and collapsed and just laid there. Cleaned her up, brought her in and when I put her back she had trouble getting her footing
I'd check her for lice/mites, keep the vitamin therapy going. See that she's eating/drinking well. Check her crop to see that it's emptying.
Hopefully she will rally with a bit of TLC. Keep me posted.
