| | Feathers, Frugality and Fashion - |
 | | Chicken feathers resemble wool in that they are made up of keratin, a hard structural protein also found in hoofs and fingernails. |
 | | Like more conventional fibers, feathers and rice straw can be treated with chemicals and enzymes to break down non-essential components, then spun into thread with existing textile machinery. |
 | | Chicken feather barbs, in particular, have a lightweight, honeycomb-like internal structure that gives them superior insulation properties, making them ideal as a substitute for wool or synthetic fleece in vests and winter coats. |
