I have four Black Sex-Link hens. They are about four years old and still lay as many eggs as they did when they were pullets. As layers you could scarcely ask for a better bird. They lay big brown eggs regularly. It's not uncommon for me to harvest three eggs a day from the batch of them, and sometimes four. They are friendly, resistant to disease, vigorous, and worth every penny you pay for them. Their only problems are that they don't go broody, and they are not pure breeds. But if your looking for good eggs and tame hens, these are an excellent choice.
