Breeding Coloured Wyandottes

Black is the opposite of white, where blue is the intermediate between the two. There are several types of white in exhibition poultry differing in the way they were formed to give them their lack of pigment. First is the "splash" (splashed white) which is like a "washed" out black fowl. When a Splash fowl is mated to a blue fowl, this results in both blue and splash birds, but when this splash bird is mated to a black fowl, 100% of the offspring will be blue. White can also be a "sport" bred from a coloured fowl as is the case of the Large White Wyandotte which was a sport from the original Silver Laced. This makes it recessive to Black, unlike a lot of other breeds.

Breeding Cuckoo:

Breeding Large Barred Wyandottes:

This requires introducing another breed to produce the barred pattern such as a Barred Plymouth Rock. First cross a Barred Plymouth Rock male over Black Wyandotte Hens. This cross should produce all rose combed Barred birds because both Rose Comb and barring are dominant.

Mating brother to sister will give 25% single combed offspring. Discard these. Only 25% will carry pure barred genes, and 50% impure genes. To Check to see which of these Wyandottes are "pure" barred, you can single cross them over a Large Black Wyandotte, and only if 100% of the offspring hatch barred do they to carry pure barring(any Black offspring, then they are impure barred)

Breeding Cuckoo Wyandotte Bantams:

The white in the White Wyandotte bantam carries a gene for barring, which is dominant over Black. This makes it easy to breed cuckoo bantams. Mate a Black Wyandotte Bantam male to White Wyandotte bantam hens, and cuckoo offspring will be produced. Take the best females and mate them back to thier black father. Pick out the best pair from this cross, and hatch plenty of chickens. Good Cuckoo males will be produced, half of the females will be black and the other half cuckoo. If you want to test the males for cuckoo purity, single mate them back to a black female, and if any blacks are produced he is impure. If all cuckoo offspring hatch, then he is pure and is the bird to keep. You can keep breeding cuckoo to cuckoo, but be careful not to let the colour get too light or dark.

Breeding Blue Wyandottes

Black = BB
Splash = bb
Blue = Bb

Matings:
Blue (Bb) X Blue (Bb) = 50% Blue (Bb), 25% Black (BB), 25% Splash (bb)
Blue (Bb) X Splash (bb) = 50% Blue (Bb), 50% Splash (bb)
Blue (Bb) X Black (BB) = 50% Blue (Bb), 50% Black (BB)
Splash (bb) X Black (BB) = 100% Blue (Bb)
Black (BB) X Black (BB) = 100% Black (BB)
Splash (bb) X Splash (bb) = 100% Splash (bb)

There can be many shades of blue, and some will come out darker, and others lighter. Even though "Splash X Black" produces all blue fowls, you can only expect about 50% to show the desired blue colouring. Also, to achieve the above percentages you would need to hatch many chickens.

It is better to say, for example, that by crossing two blue fowls, there is a 50% chance that a blue chick will hatch. Why?? Following Mendel's law of inheritance, each chick recieves two genes, one from its mother and the other from its father. Blue (Bb) is made up of both black (BB) and splash (bb). Using basic probability we have 4 combinations from crossing Blue (Bb) over Blue (Bb) which are:
BB, Bb, bB, bb
This is because each chick recieves a single gene from each parent.

Breeding Crele Wyandottes:

Golden Creles can be produced by mating a Partridge male to cuckoo females, then breeding the best pullets back to their Partridge father. Silver crele is less attractive, but can be bred by using a Silver Pencilled male in place of the Partridge outlined above.
