My TSC usually has between 4 and 6 stocked bins. One for ducks(which they usually go to clearance because no one wants 24 ducks @ $6 each), a bin of red sexlinks, a couple bins that change every week, simetimes sexed BJG's, sometimes amberlinks, white leghorns or brahmas, a banty bin mostly containing EOGB's and silkies, and a cornish x bin. If they have a bad week they usually double up the birds that dont look alike, like amberlinks and red sexlinks so they can order more. Sometimes they also have two bins of ducks, usually about 2 weeks age difference.
