It seems like half of northeast MI orders from Townline. My local feed store gets chicks from them so I'm ordering 10 of the Mountain broilers (I think they're called?) and some orps a rocks. As far as I know everyone I know who has ordered from them has been happy. We haven't ordered directly though, just through the feed store.
If you tried calling today, it's possible they don't staff the office on Sundays.
