Hi everyone, could anyone tell me what type the white 2 are please ? They have more black around the neck like a collar but lightly speckled black everywhere else . The farmer said they were a rareish breed but can't remember what type they are . We thought they could be erminette but then looking at pics they could be light sussex too ...also one has pink feet the other a lilac colour feet if that helps ( we are new to owning chickens lol )
Thank you in advance xx

They look like Silver Lakenvelder

Did he keep his breeds pure or could they be from a mixed flock?

Lakenvelder's are completely black in the neck and tail, not spotted.
