I saw that this turkey was hobbling a little yesterday, but figured that it had a bit of a sprain and that it would heal (they have been starting to feel thier oats and are practicing going over the top of their grow pen), but now the turkey is down and I am not sure if it will make it through the night, but need to know what is going on. Yesterday, the turkey's hock (the main joint on their leg) was a little swollen, today, it seems to be affecting the other hock and both feet, so the turkey can't stand up. I know about joint issues related to feed and these guys have all been fed the right ration for the right age and, so far, this is the only turkey that is having this issue. What is causing this? Unfortunately, I am new to raising turkeys.
