Yep, all that is correct. The veins and arteries are side by side and act as a heat exchange system. They can also control the amount of blood flow to the feet and therefore the temperature and degree of heat loss in their legs/feet.
If your duck's feet feel hot, you know they are trying to lose heat to cool themselves down. If they have cold feet they are trying to conserve body heat by reducing the blood flow through the feet.
