You are lucky. I've heard of many many horror stories about the auction. Many are about Mycroplasma or being sold a pullet that was actually a 3+ yro hen
I'm glad you had a good experience though b/c I guess they all can't be bad or that place wouldn't be selling any poultry. I just hope if you do buy again you Quarentine your new feathered friend for a min of 3 wks b/c it takes 21+ days for Mycroplasmas AKA: CRD to rear it's ugly head and Lower Middlesex and Lower New Haven county had a huge outbreak this past year
