Anyone with chickens selling eggs on or near the ladder?

I'm looking for a local source of eggs, used to keep them before moving to London and miss the vibrant yellow yolks and more importantly eggs from happy, cruelty-free hens! 

Anyone know of someone in the area who sells eggs? I'm near the northern end of the ladder but happy to travel up through wood Green, south past Finsbury Park, or East/West in the same area.

Thanks!
