hi, we are having a similar problem with four of eight of our turkeys. they are not quite two months old. we've had turkeys before and never encountered this. the "knee" is a bit swollen and the leg is bent-but only on one side. this results in the turkey unable to walk on that foot and ends up hobbling. what began as a limp has progressed to an inability to walk. the turkey who is the most severely affected will attempt to stand and then sit back down. is it pain, frustration? we've looked on line for some possible causes but nothing fits their symptoms. how is your turkey? any help would be greatly appreciated, our hearts are breaking watching these poor dears...
