Did you know that turkeys have something like a breast sponge that holds fat and protiens. Much like a camel and its hump. During breeding season the toms are less concentrated on food and water. When they need nourishment they will draw from this "breast sponge". So dont rely on food sources and water sources too much during the spring season. Find his roost and find where there are hens and you will have him. Also,birds taken in the fall tend to be bigger than birds taken in the spring. In weight. They are bigger in the fall because there is more mast crop for them to eat therefore they have more to eat and they will weighmore. In spring season there is not much mast crop yet, plus they are concetrated on breeding, not eating.
