No. Geese and ducks have one of the most effective circulatory system of any animal. The veins carrying the warm blood (to the feet) and the veins carrying the cooler blood (away from the feet) are so close together that the warm blood warms the cooler blood and prevents the animals feet from freezing. However, they must feel a little uncomfortable. Ducks and geese will sit in the water even in the coldest temperatures because the water is always warmer than the land.
To make veins more visible on your arms, you can try techniques such as increasing blood flow through exercise or using a tourniquet to temporarily restrict blood flow.
