If it works and the goat is happy then this is brilliant. :-)
We had a neighbor long ago who bought some goats for the express desire of getting fresh goat Milk. It never did work out. From what I learned from them back then Goats unlike most Cows aren't wild about being milked. I know for certain that they tried it squatting right alongside them while they were standing on the ground, so maybe they didn't read about one of these stations? I never saw anything like this over there anyhow.
