I was just reading an article about how commercially raised hens are considered "spent" at the age of 2? In other words, they don't produce as many eggs. And they can live to be about 10, but they are normally killed and replaced with younger hens who produce more eggs. I worry that I will be attached to my little backyard hens, and will want to care for them throughout their lives, eggs or not. But... I do want hens for eggs, primarily. What to do? How do you handle this? What has your experience been with hens of different ages? Is breed a factor? When hens "slow down" later in life, how much do they slow down? Do they produce 1 egg a week? 1 egg per month? Thanks.
