A few months ago, my 2 year-old australorp started having trouble walking, lost weight, and died. I brought her in and tried my best to help her, but nothing seemed to stop her from wasting away. Now one of my others - a 4 month-old pullet - is having trouble with one of her legs. Her hock doesn't seem able to support her weight and buckles when she walks on it. None of my birds are vaccinated for Marek's, but I haven't gotten any new birds for 6 months - and those are doing fine. However, there are tons of wild turkeys around. Could they be passing something to my chickens? I've looked all around this forum for info, and found a bunch, but couldn't find any regarding a condition in which one leg at a time is affected. I have my pullet inside right now and am giving her vitamins and electolytes mixed in with oatmeal. I'm hoping it's either a vitamin deficiency or a hock injury, and would really appreciate any advice or insight y'all might have! Thanks!
