This is an autosexing breed of hybrid. This means you can sex the chicks by their head colour, males having rougher spots of colour on their heads which spreads across the body.
They come from cross-breeding of Brown Leghorns, Barred Plymouth Rocks and Araucana in the 1930s.
The eggs come in shades of blue through green and this hen can lay 180+ a year. The hens are also superb mothers and will foster well.
