TIP What is a mule?
A mule is a crossbred ewe sired by a Bluefaced Leicester ram, and a halfbred is a crossbred ewe sired by a border Leicester ram. In most cases the crossing sire is put to a hill ewe, so, for example there’s a Scotch mule (Scottish Blackface ewe crossed with Bluefaced Leicester ram) and there’s a Welsh halfbred ( Welsh mountain ewe crossed with border Leicester ram.)
However, just to confuse matters, there are a few exceptions to these general rules. One such is the Kent halfbred, which is a cross between a Romney and a Lleyn. I think that Kent halfbreds were quite popular in the 1980s, but you don’t hear much about them these days.
