It's a breed developed by Hy-Line International, the Silver Brown. When we went to Mozambique—layers will typically lay between 19 and 52 weeks of age, say, or even go later—those birds were 60 weeks of age and they were in amazing shape. Mortality was really low. They were still producing a lot of eggs and were very healthy. I don't know that they're specifically adapted to sub-Saharan Africa, but I know they're quite robust, and that is exactly the same breed that we will use.
Also, you're absolutely right. At the end of the lay cycle, you have a whole new source of protein in the chickens, so that's where the part about sustainability comes in. You use everything.
