We went last night. They sold off a bunch of goats, a handfull of calves, several rabbits, some cocketiels, pigeons, quail, ducks, and turkeys in addition to the chickens. Chickenwise, I remember Polish, Silkies, Barred Rocks, Buff Orpingtons, Marans, RIRs various bantams, lots of mutts/unidentified birds. Prices ranged from $1-15 a head. Most birds were sold in cages of multiple birds.
All in all it was an entertaining evening and seemed to be a well run auction.
It is most assuredly very rustic, not much evidence of the country club set in attendance. Clean out your coop right before you go and you will fit right in. : )
Edit: they were running a seperate auction outside at the same time with tools/hardware etc. Something for everybody!
