Chickens are animals that can be taken care of in the game, Harvest Moon: Island of Happiness.
Once you ask Gannon to build a chicken coop, the next day Taro will come to your place and give you a chick, you will then have to name it. In a couple of days, after feeding the chick daily, it will turn into a chicken. You will get an egg daily, if you feed. The average life span for a chicken, if you feed it daily, is about four years. If your chicken gets too much stress, as with cows and sheep, your animal will die. If this occurs, then your friendship points with ALL of the characters will drop drastically.
