Hi, I'm new to turkeys this year and we just got a grab bag of two of them. One died at three weeks with no warning signs. The other one is still going strong but we were wondering how to tell if it is a male or female and at what age the snood should start growing if it's male? He/She's very friendly and even sits in our laps and poses for pictures and wants to follow us around the yard with the geese but we don't let it because we're afraid that we can't catch it to put back in the pen. At 7 weeks it is 2 1/2 lbs and we've never seen it strut. It is beginning to gobble some though. Also, how long should we feed it starter mash? We've moved the other birds onto grower ration pellets.
