Every evening one of the chores is to separate Comet from her mother, Hailey.
The winter of 1986 found me fencing dams in back-blocks NSW for the Soil Conservation Authority. Night after night we scoured the sky to see a glimpse of Halley's comet. After weeks of frustration we finally met someone who knew where to look and we could then enjoy the spectacle.
So when our Jersey heifer Hailey produce a calf, it seemed logical to call her Comet.
If Comet stays with her mum then it is not worth milking. If we remove Comet altogether and wean her then when we want to go away for a night we would have to find a stand-in milker (which we don't have) or milk production would really start to wane.
