I had one of my production girls that fell off the roost and I guess landed funny. SHe couldn't put any weight on the leg. I knew it wasnt neuro b/c when I put my finger under the injured foot her toes would wrap around my finger she would also resist a little so I knew there was still muscle tone. I did not take her to the vet so I don't know the exact diagnosis....perhas somekind of sprain... Anyway, I seperated her from the rest of the flock by putting her in a pet carrier. I doctored her for about six weeks..she only has a slight limp now but is fully functional. I first named her Gimpy but have since named her GIGI..The flock rejected her so she is now in with the silkies and is thriving! I hope that helps and that your girl mends soon...
