Please do choose your abattoir carefully! There are, or used to be, regulations regarding the slaughter of goats i.e. that they should not be slaughtered in front of other animals and not have others slaughtered in their presence.
Whether or not this still holds true I don't know.
Goat meat is as good a meat as you can get, tender, tasty and lean.
Taking anything to slaughter is not nice, even killing a chicken at home is stressfull, but if you can do it calmly and with the animal's welfare in mind you will find it's not the dreadful ordeal you imagined!
