Hi There!
And Welcome aboard!
Boy do I have a great day for you!!! On Saturday the 26th there is a Poultry Swap in Rickreall, Oregon and there are going to be quite a lot of birds, supplies, crafts, etc. being offered for sale. There are about 80 booths in 2 barns at the Fairgrounds. You can learn more about it on their
web page and their FB page. Search "Oregon Spring Poultry Swap". Even if you don't buy it should be a very entertaining day!
If you do choose to buy off CraigsList, please be very careful about checking for parasites, injuries, health, etc. There are a lot of hatchery birds sold from home, too. If you want good stock be sure to ask about the parentage. And if you can wait, BGMatt's suggestion of going to a show in the fall is a very good one. Check out Washington Feather Fanciers and PNPA for their show schedules. These shows are a wonder to behold especially if you've never been before.
There have been a lot of folks hatching in the past few weeks so over the next couple of months there will be more birds of the age you're looking for become available. Good Luck and Enjoy!

I was just told that Diane at the Feed Bin in Rochester is a very good source. That she deals only with breeders. It's a small feed store with great service. The Feed Bin....360-273-7440
