Charles Mamboleo, who runs a farm in south-western Nakuru County, discovered the cow feeding on a sheep one morning, having apparently gored it to death, the Daily Nation website reports . Fresh food and water couldn't tempt the cow, and another sheep met its end the following day, the report says. "After the first incident, we thought the cow was starving, so we increased the supply of fodder and water, but it still continued chasing after sheep," says Mr Mamboleo.
