I will have CCL roo over BO, GLW, Marans, and maybe Dorkings hatchings eggs...in the spring...If you want to do a bater, Sally Sunshine (who used to be on here) had pretty good instructions...on this site....
The only pure breed CCLs I know of is H&H near Harrisburg....I do have a contact from SC who said she will be traveling to State College to visit in the summer and have some pullets or eggs to sell along the way....who knows....
oh my responding to myself.....lol...forgot to add this link....

There is a hybrid CCL: thread .....https://www.backyardchickens.com/t/825092/cream-legbar-hybrid-thread ....my understanding is limited, but...depending on the cross....you may have some auto sexing carry through....but it may not be perfect or carried forward....
