If you're okay with some bantams, I would check out Ideal Hatchery.
MPC is sold out of most breeds through the next half year. I'm hoping they are just slow in updating their online catalog. There's also Meyer Hatchery where MPC has their hatching space. I can't get their catalog to come up, though.
Ive exhausted my brain searching for a hatchery that has the breeds I want. So here I am to ask the experts. Which hatchery has the most breeds? I want some: BLRW, LF cochin, Marans, Orps other than buff, Sussex, Dark Brahma.
