The Chaileybrook flock is largely based on three main families which can be traced back for a number of generations and each of which brings with it a unique set of characteristics.

Having refined these families over a number of years we can be confident that any stock bred at Chaileybrook carry the characteristics which have made the Southdown breed and the Chaileybrook flock what they are today.

The first of these families of the U8 family, with this line responsible for breeding a large number of show and sale topping stock and often among the animals picked out by visitors for their character and conformation.

Notable members of this family include Chaileybrook 05/0002, interbreed champion at South of England 2006 and dam of former male record holder Chaileybrook 12/0008 as well as being dam of former joint female breed record holder 13/0002.
