The above diagram is from R.C. Punnett for the creation of the Gold Legbar which was the precursor to the Cream Legbar..Crele is a Game colour, it is made by a combination of Barring & (gold)Duckwing . Black Breasted Red is a male colour/pattern common to ER Birchen crow winged birds; eWh Wheaten & eb Brown duckwinged birds. The latter make pseudo Crele looking birds.
Crele is an autosexing bird that can be made following this guide, substitute Barred Rock with a Cuckoo or barred bird of choice ( this depends on the breed you are wanting to make ie hardfeather Cuckoo OEG, softfeather BRock,Cuckoo Leghorn etc) and substitute Brown Leghorn for Partridge OEG,Welsummer or Light Brown Leghorn etc.
In OEG the darker heterozygous male e+/e+ B/b+ are shown as Crele, as are the hens. The lighter homozygous e+/e+ B/B males are called Mackerels, there are no light Mackerel hens, as all hens are hemizygous e+/e+ B/-.
Silver Crele can be made using a Silver Duckwing hen.
