I have 4 pet Narragansette turkey that are about 3 months old....snoods are all small, necks are just starting to turn reddish with a hint of blue/gray? but heads are still kind of sprinkled with tiny feathers. No one has attempted to strutt or display. I was hoping for 2 of each sex but I think I have all one- just not sure which. No one is making any distinctive sounds yet either... When do the snoods develop- at what age should I be able to tell what sex I have by external features. Thanks.
