If you have trouble sleeping, the attach guidance from defra will quickly solve the problem.
http://www.defra.gov.uk/foodfarm/farmanimal/welfare/transport/documents/watoguidance180208.pdfThis will give you endless hours of amusement as you watch what was clearly the work of several mandarins creating tortuous sentences that make a complete nonsense of any original intention, and into the farce that is Defra EU implementation.
The regulations allow transport that is not in connection with an economic activity, and give some exemptions where it is an economic activity.
Once such exemption is :
“when the animal is an individual animal, is accompanied by its owner or other responsible person and is fit for the intended journey “
Defra then expand this and state:
“Individual animal” should not be taken to mean that a single animal in a vehicle is all that would qualify for the individual animal exclusion. Our interpretation permits more than one “individual” animal to be transported in the same vehicle provided that each is accompanied by a single person who has responsibility for it during transport."
So if you hire a coach and put 42 adults in it, it can tow a trailer with 42 sheep in it !!
