Dear foreros, I've started this thread by accident in the Slavic forum and, according the answers received, it seems to be quite interesting. In Spain, in Italy and in France (at least) eggs are sold by dozen or half a dozen but in other countries (Hungary, Croatia, Poland...) they use 10 units, 6 units and even 60 units! What's the unit used in your countries? What's the origin of counting eggs by dozens? Thanks.
