I have a 5 or 6 month old Pullet that had a sudden onset of 1 leg paralysis. When we first got her home about 2 months ago she had a silimar incident where she appeared very weak and unsteady. I was concerned about Mereks,but I gave her some supplemental vitamins and she perked up. The only think was that her growth rate was quite slow and she's still smaller than I would expect her to be. She was completely healthy until yesterday she started having an issue with one leg. She stuck it out staight to walk and was resting much more than usual,but still eating and drinking well. I gave her more supplemental vitamins and she didn't seem to worsen over the way. Today she cannot support her weight at all. I helped her up and she tried,but her leg was not cooperating. Could it be a reoccurrence of Mereks or something else? Her feet look fine and we introduced 2 new chickens about 2 weeks ago, but they were from the same farm she came from and all in that flock are healthy. None of our other chickens are having issues.
