At 6 weeks, these look beefier than a standard white leghorn, and some have dark legs and all have pea combs (great for winter). Can't wait to see the production of these, and the color.
The chicks with darker shanks are pullets, they inherit their id+ sex linked dermal enhancer from their EE Sire, the cockerels have inherited the sex linked dermal inhibitor Id from thir dame and one copy of id+ from father, so they are Id/id+ and pullets are id+/-(a void) Id is dominant over id+
