I know Meyer Hatchery is located in Ohio and they have Polish (not sure what they have available this time of year). Here's a link to them in case you need it: https://www.meyerhatchery.com/productlist.a5w
Im having the same problem. I have been asking around and none so far. You might try going to the Ohio National Poultry Show in Columbus, this weekend if you can, theres a lots of sales there every year. Im hoping to pick up some blue polish hens there this Saturday. Good luck.
I do currently have one male blue polish for sale, he's about 10 weeks old.
I am afraid to add only one to my flock of 5. Plus my city only allows hens. Meyer Hatchery in Polk Ohio seems like my best bet. Only 45 min away and have a nice selection. Yay .... Bring on Spring!!!
Being far far away from where you live I can't help you much but I will add, as a Polish lover who knows how hard it is to find adult birds - I'm jealous that you do in fact have access to Ohio Nationals. It's an excellent poultry show to go to, one of the biggest, and there's often Polish of any color for sale there. They're not hatchery birds either, so they're bound to be quite spectacular. Also in most cases, bigger and chunkier than Polish found outside the show ring.
