I recently bought 2 new 6 month RIRs. One was very aggressive at first but has since settled in with the other hens and ducks. The 2nd hen was doing ok at first but now she doesnt look good. She lays around alot and holds her wing out to the side. When she lays down she spreads her wings out and stretches her leg. When she walks, she walks like she is walking on glass. Her feet overlap. I have checked for any changes on her feet and there is no swelling, redness, or cuts. I had her separated in a x-pen and was giving her wet cat food (to get her back in feather with the extra protein), powerade (for electrolytes), and grass. She was very upset being separated so after 3 days I put her back out with the others. No one is picking on her and she really enjoys the sun and dirt. Poop is normal, eyes are clear, and no cold sounds. Any ideas on what could be wrong with her feet? Thanks in advance.
