Although Transylvanian Naked Neck chickens look more like a Frankenstein cross between a chicken and a turkey, they are 100% chicken. This is how they got the name Turken, as many people truly believed that they were a Turkey Chicken crossbreed.
The lack of feathers on the neck is an adaptation to help them stay cool in hot climates.
I used to have a few of them. Everyone who saw them thought they were diseased, but they were just my cute mini vultures to me 🤣
