Wyandottes- breeding with blue
Recently I have been experimenting with blue in my laced wyandottes. It is a fairly easy way to add a bit of variety and experiment with a new colour, without having to get all new stock. When I refer to blue, I am talking about the lacing colour; eg blue takes the place of the colour black. I will also mention the colour 'splash' which is simply a very light version of blue, appearing almost white. (see a picture of 'Mr Splash' below).
For the purpose of this explanation, I will refer to the Black gene as bl, and the Blue gene as Bl (as it is dominant). each bird has two allels of the gene at the lacing colour locus; one from each of its parents. They then pass either of these genes on to their offspring.
A regular wyandotte with black lacing will be: bl/bl
A wyandotte with blue lacing will be: Bl/bl
A wyandotte with splash lacing will be Bl/Bl
Blue X Blue (Bl/Bl x Bl/Bl). This will give you 25% black (bl/bl) 50% blue (Bl/bl) and 25% splash (Bl/Bl).
Black X Blue (bl/bl x Bl/bl). This will give you 50% black (bl/bl) and 50% blue (Bl/bl).
Black X Splash (bl/bl x Bl/Bl). This will give you 100% blue (Bl/bl).
Blue X Splash (Bl/bl x Bl/Bl). This will give you 50% blue (Bl/bl) and 50% splash (Bl/Bl).
Splash X Splash (Bl/Bl). This will give you 100% splash (Bl/Bl).
