Keepers dye sheep pink

Parents should prepare for some tricky questions from their confused children if they head to a a New Zealand nature park and find this flock of pink wooly mammals grazing on the hills.

The extraordinary sight is causing a sensation at SheepWorld, near Auckland.

Park bosses originally dyed the animals as part of breast cancer awareness week, but it proved to be such a hit with visitors that they decided to keep them as a permanent feature.
