You don't have it because the birds are R/r+, when you get to a homozygous one, you will stop producing single comb F1s.I dont have an issue with fertility i just want a laced/mottled bird lol the single comb is already taking forever to get rid of
R/r+ males will outcompete R/R males if left to free range. Your best bet is to find out the R/R males(by cross breeding to single comb breed) and lock him with known R/R females, otherwise the R/r+ males will produce higher amount of offspring than the R/R one
