I don't put where I got my stock from on my site because I got them from many places and over time, combined what I got to something that is uniquely mine. There for where I got them is now, not relevant. so.. I dont' list it.. many people don't list where they got their birds for the same reason.. over time, they are just your birds.
Funky Feathers,. I like your website. I like to see lots of photos.

Then in that case, I would put something like: Breeding the (breed) to the standard for 20 years. Or whatever applies. At least that lest buyers know this isn't your first year breeding your hatchery stock and thinking you are a poultry breeder.
I'm not particularly impressed with his site either. Not that it's bad, but there's nothing that makes me think 'Buy from them'. And he doesn't list the strains he sells.
