Forming an orderly queue

These well mannered, psychedelic Texel ewes are patiently waiting at the entrance to the Neolithic burial chamber of Maeshowe. 

In the Autumn a sheep's thoughts turn to romance and it is at then that the rams are released to do their duty. The shepherd is of course interested to know which of his/her ewes have been mated. The information that they need is acquired by fitting the ram with a chest harness that holds a special, greasy, coloured crayon (or raddle, sometimes spelled reddle). Ewes that have been mounted are as a result clearly marked, as is the case with these ladies. One of them seems to have fallen into the arms of both the  red and blue rams.
