I've got a chicken neck too, 15.5". I bought a neck harness but I can't really find time to do them during the day. 15.75" calves flexed but I literally never done a calf raise. Oh look I'm 1:1:1 on everything but probably doesn't count for people at 19% BF ; ;
I think a thick neck is pretty aesthetic. I need to get mine bigger but afraid to do any direct trap and neck work, since laying off that and developing my lower traps it's helped my shoulder problems a ton.
