Well, I can answer my own question - my local Grange Co-Op (and apparently the one in Medford, too) get their chicks from Privett Hatchery. Can't say I'm impressed with Privett, as so far 4 of my 6 "sexed pullets" aren't pullets. I'd have expected at least one or maybe two out of six, but four? That's the way the chicken, errr, bounces, I suppose.
Have an ad up on Craigslist offering them for free, but, judging by all the other ads, this isn't going to work. I went into the idea of having chickens knowing that, at some point, it would be necessary to put a chicken down (because of illness or injury), but I really wasn't expecting to have to do it just because I have too many roos.
