We have a 3-month-old white turkey, feed store white. He's 'brothers' with a bronze feed store turkey. They both have the itty bitty snood that just sticks out, like a hen's. More than a week ago, I noticed his snood was gone. The stump was still there, with a scooped-out area. No blood, no nothing, and no snood. It still looks the same a week later. What happened??? Will it grow back?
