I was out cleaning animal pens this morning- it was so pretty today after so much bad weather. Timber was doing the pregancy moan and groan while lying in the sun chewing her cud- her eyes half closed. Then I thought I heard an sort of harmony going on- Dottie, who is not pregnant, was also lying in the sun near Tim, chewing her cud and harmonizing with Tim's "song." She was just joining in to be companionable- mostly she added her shorter song between Tim's long, drawn out one but sometimes she made repeated grunts to add a beat to Tim's. Just had to stop and listen for awhile.
