I have a Narragansett tom that is about 5 months old...a couple weeks ago I noted that he was limping and his left leg was slightly rotated outward. I thought he might just have injured it. But it didn't improved then this week it continued to rotate outward until it is beyond 90 degrees and he is really struggling. Another tom of the same age also just started to show symptoms of his left leg slightly rotated and being knock-kneed. Could it be genetic, diet? they are on good game bird feed...same as I've used for all my other turkeys over the years
