This little one is a Barnevelder. A dutch breed, beautiful dark brown feathers with black lacing and will lay dark brown, speckled eggs.
The white ones: Light Sussex up top, will be white with a black necklace and black tail feathers; down the bottom is Faverolle, very rare, has five toes (see them?) and will have a beard.
And this one I think is a cross between my Silver Laced Wyandotte rooster and one of my Blue Orpingtons.
They are so funny when I drop teeny bits of broccolli and comfrey into their box. Think of a gang of kids having a lolly scramble! Except there are no parents to step in and comfort the losers.
