Just a tip: if you know exactly what you are looking for, make deals with breeders to pick up birds at the show in advance. You may see what you want and buy it in the sales area, but more often than not, the nicest birds are being sold "behind the scenes" to people who reserved them in advance and asked to pick them up at the show. The best breeders in the country go here, and sometimes you can arrange for them to bring you something.
If you're just going to see whats there and are open minded about what you might get, the sales area will surely have a nice variety of good quality birds to choose from.
Another tip, walk the aisles of the show, if you see a bird you like you can check the coop tag and look up the breeder and try and get in contact with them.
I will definitely be there for the 2017 show. Maybe I'll see you. But I doubt you'll find any of my birds up to par with some of the others
