My family and I got some red sexlink chicks, white leghorns and 4 cornish rocks from TSC this spring. We planned on eating the cornish rocks but then we decided against it because they were so sweet (we should've just done it, lol). Now, I was just reading that they wont live more than a year and that their combs will start to turn purple a day or two before they are going to die. If this is the case, when I see their combs turn color, would they still be good to cull and eat?
