Ok, here's what I have to contribute. Your boy is 1/2 your flock. The texture of the skin on the comb and the shanks is indicative of the texture of the rest of the skin on the bird's body that you can't see. This is the type of skin he has to pass on to his get. Now a good meat bird needs a skin that is fine and smooth in texture. A good laying hen needs skin that is fine and smooth in texture for 2 reasons.
1. it allows the skin to stretch as the reproductive organs swell when laying starts. This makes it easier for the hen to lay her eggs.
2. Coarse-textured skin tends to have a build-up of fatty tissue underneath it. This fat keeps the skin from stretching when the hen starts laying. Both the coarse skin and the layer of fat, singly or together, keep the bird from being a better layer.
So , if you want to produce better meat and egg chickens, don't use these boys. The comparison of their comb and shank skin to what proper skin in these areas should look like, is akin to comparing burlap with fine silk.
