RE: couple easy questions
1. A jake has a short beard, hasn't quite made the "curl" downward. A jake also has a "cut off" gobble, most of the time. The center tail feathers, during strut, will be longer than the rest.
2. Most of the time I don't use decoys, but i always carry a jake and a hen. If I find a tom on a hill and can't get to him undetected, I'll put them out and call the tom downhill. They say you can't call em downhill but I have on more than one occasion.
