Blue coloured chickens
There are 3 genotypes for Blue coloured fowl.
The gene is Lav Lavender, the colour is Self-Blue in the US, Lavender in the rest of the English speaking world & Pearl-Grey in Europe.
Andalusian Blue Bl is the gene, the colour can vary dependant on the modifiers present,
it can be a Laced Blue, the norm in the USA, when the Pattern gene,Columbian & Melanotic are present;
or an unlaced Pigeon egg Blue, more common in the UK & Europe, when these modifiers are not present. This gene expresses Blue as a heterozygote, Splash as a homozygote.
Smokey is the gene I^s, the colour is a true breeding blue. This gene is an allele of Dominant White.
