we just got 3, 4 week old narragansett poults at what age should i be able to tell what gender they are.We just sold our bbb turkeys for someone to butcher.Do the narragansett turkeys show there gender ealier than the bbb breed?A couple of em are starting to loose the short fuzz on the back of there heads now does that mean anything?Also what age will these little guys start to gobble?
