Golden Chickens who eat every day mature after 3 nights have passed. A mature and fed golden chicken produces a Golden Egg every day, which can be placed in an Incubator to hatch another golden chicken, or sold for 500g.
A very rare and special egg with a solid gold shell.
Golden Chickens may be sold the same way as normal chickens. The more hearts the animal has, the higher its sell price. A new-born chick sells for 252g, and a maximum-heart Golden Chicken for 1,040g, the same as for normal chickens.
