Looks like a lav to me. Your black must be split for lav. All your chicks from the lav hen should be 50/50 then (50% lav/ 50% splits), but watch for clean faces. Can't tell if that chick is clean faced or just wet. If they don't have muffs at hatch; they won't get them later....you can save yourself some feed if you know that going in.....Good Luck!
