I have a 22 week old blue copper maran pullet who started limping about 2 weeks ago and I still can't find what's wrong. No bruising, swelling, or broken bones that I can see, her feet look fine, no bumble foot signs and she hasn't gotten any worse (but no better either). She eats, drinks and free ranges with the other gals like its no big deal, she just limps when she walks. Occasionally she will lay down and rest for a while but other than that she's acting normal. I have given her a couple doses of poly-vi-sol without iron because I had it on hand but it didn't make s difference. She's on grower feed and gets a few table scraps here and there and the occasional cup of yoghurt shared between 9 laidies and one roo. Any thoughts? Should I put her in a crate to make her rest? I did once but it didn't last long because she whined the whole time
