Is the bottom of the feather shaft above the skin?

The feather consists of the lower part – the quill, which is located in the skin. A fan was formed on top of the skin, on both sides of the rod. The fan consists of barbs. There are barbs of the first and second order. The barbs of the first order grow from the rod, and the second – from the first. They have hooks that hold them together. Most often there are no hooks in the lower part, there the feathers are more fluffy. This part is more suitable for keeping warm.
