Jennys will display sometimes too... the smaller size and daintier build is what says jenny to me... also, the fuzzy line up the back of the head... but the caruncles look kinda big too... *could be* a slower maturing jake, but I am thinking jenny...
Watch the snood... if it doesn't extend much further then I'd say jenny...
Hens will have tiny feathers down their necks and on top of their heads. Toms will be bald. As best as I can tell from your pictures you have a Tom and a Hen!
