I hadn't seen the "rehome your unwanteds" ad coming from the same place, probably because I was only looking in the for sale section. Now that I look more closely at the CL ads, and someone clued me in via PM that this is "Duck 'N' Coop Hatchery" and I found some info on that place on the old Michigan threads, I think I'll avoid him. It seems like a place that big, moving that many birds, ought to be NPIP certified. I know NPIP isn't any guarantee, but as others have noted, taking in all sorts of birds and reselling them combined with the volume seems very risky.
