As happens with most pregnant cows, about two weeks before giving birth, both cows' udders swelled with milk. They were pastured with a herd of Scottish Highlanders that included cows with nursing calves. Calves are always hungry and can be opportunists. One calf named Hamish, enticed by Keeper's massive teats, decided to nurse on Keeper-who let her! Hamish was a moocher, and Keeper was a willing "milk machine."
