To provide us with eggs. You see, they are domesticated. For thousands of years they have been bred to do just what they do today. Over time, chickens that tended to lay more eggs for longer periods were kept and bred over thousands of generations. Presto--breeds like Leghorns and Rhode Island Reds that lay more eggs than most other breeds. Other breeds of chickens over time were bred not for how many eggs they could lay but for meatier thighs and breasts (broiler chickens) and some breeds for both qualities so you could have your eggs and still get good meat when they stopped laying because of age. When you say "most other birds lay fertilized eggs" this is only true if there is a male of the breed around. As long as there is a fertile rooster doing his job with access to the hens, every egg the hens lay will be fertilized. In other species of birds that perhaps only lay a couple eggs each spring, it may be that something the male does triggers that egg laying.
