when your judging laying hens, your looking for laying ability, and a good hen would put all her effort in to laying eggs, so:
1) look for pigment in the legs and beak, Keratin provides the yellow in the pigment, but keratin also is the shell of the egg, so if they have less pigment that means that they devoted more to the egg then to themselves, this is a quality of a good laying hen.
2) good hens wont have good/ new feathers, look at the primary feathers, if they look old then its a good layer, if they have grown new feathers then they are not devoting all they can to laying eggs.
3) look for fat deposits around their vent, if they are storing fat then they aren't devoting all they have to laying.
