I have a croad Langshan female, Dominique females, red females uncertain lineage(came in a mixed heavy breed box from cackle) , white rock females, welsummer females, Easter egger females(light green eggs) , a French black copper Marans rooster, a white rock rooster, an Easter egger rooster (dark gray) What can I get as crosses and which might be "best" for anything or particularly useful? Is the white rooster useful for sex links with the dominiques? I know the ee and the Marans could be olive eggs. If I could add one male what should it be to get useful crosses? Rhode island or new Hampshire red male maybe? Thanks.
