I've tried not to do this, but been trying to work out the breeds of my hens. They all have the same father a white silkie, so they will be a mix. The White hen with lack around the collar and tail I thinks is a light sussex mix, the brown hen has the same markings so i think she is a red sussex. I'm stuck on the other two! The white one is pure white and a slender frame, the black one is big for a bantam! they all lay white eggs if that helps.
