Because they trap more air.
Wool is considered one of the best heat insulating fabrics due to its natural properties that trap air, creating a barrier against heat loss. Other good heat insulators are fleece and down feathers, which have a high loft and trap warmth effectively.
Materials with low thermal conductivity, such as wool, down feathers, and foam, are good at trapping air. These materials create pockets of air that act as insulators, preventing heat from escaping and helping to keep you warm.
Feathers are good insulators because they have a high number of tiny air pockets that trap air close to the body. This trapped air acts as a buffer against heat loss, helping birds regulate their body temperature in cold environments. Feathers also have an outer layer that repels water, keeping birds dry and further improving their insulation properties.
Two materials that act as good insulators are rubber and wool. Rubber is a good insulator because it has a high resistance to electrical current, while wool is a good insulator because of its ability to trap air and prevent heat transfer.
Feathers are typically considered to be insulators, as they are made up of a lightweight structure that traps air and helps regulate body temperature. Feathers are not good conductors of electricity due to their low density and lack of metallic properties.
wool is a insulator
A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators.
Wool, Nylon, Cotton
feathers, they have feathers
There are many different types of insulators. Fleece is probably the best insulator that I have tested. Wool is next. But I do not know about pure wool. The wool that I had had rayon in it, so pure wool might come out with different results.Cotton and vinyl are also good insulators. I tried to use burlap, but it had so many holes in the material that it wasn't a very good insulator.

No, Turkeys have feathers.

Some heat insulators are fiberglass, polyurethane foam, and polystyrene. Two other thermal insulators used as insulating materials in building construction are mineral wool and cellular glass.
