The number of eggs any hen will produce depends greatly on her breed. Some breeds of chickens have been groomed for egg production, with selective breeding ensuring the hens will lay as many eggs as possible. Bovan goldline, Rhode Island red, legbar and light Sussex are all types of chickens that have been bred for rapid egg production. Bovan goldline may lay as many as 320 eggs per year, while Rhode Island reds, legbars and light Sussex produce an average of 220 per year. Other breeds have been created for show or meat and may not lay as many eggs. For example, show-line Orpington hens may lay about 80 eggs per year.
