Farm Animal Conundrum

[Devonian]

Cows and sheep in particular are always escaping from the fields, however, they never stray far away and can often be seen trying to get back into the field they escaped from.

Dairy cows simply wouldn't survive as they need to be milked daily, however sheep are more self sufficient and already roam free around large areas of moor land and Welsh Mountains etc and so would probably cope without too many problems

Poultry is probably different and could cope if they stay clear of the foxes, and again some breeds of pig would probably survive.

Most farm animals are however so domesticated that they are now distant relatives of their wild cousins.
