Azur have become quite common in France with the blue egg fashion. We don't have as many easter eggers as in the US. They are supposedly a leghorn / auracana mix but I think apart from the egg color they don't look anything like auracanas.It's feather sexable apparently - different than colour sexing.
this is what I found:

Colour Sexing

I already use feather sexing to 'try' to guess the gender of my wee ones with some success.
I need to read up on this also apparently. Oh and the Azure Blue and the Noirans (which apparently have feathered legs!), are also part of the Hendrix Genetics group).
Noirans are like Lily and Kara, a harco x Marans mix.
Harcos are a dual hybrid marketed by the Hungarian company Balbona tetra and they are a red black RIR / Plymouth rock mix.
The names belong to Hendricks but those type of mix are done by many breeders.
