I've milked them, put their milk in my tea, and made halloumi, ricotta, paneer, cream cheese and labna (boursin-like) from the milk. (In 4 days. Each cheese takes literally 24 hours to make. Or rather, about 15 minutes of effort over a 24 hour period.)
Every morning and evening, before milking them, I've given them hay. A lot of hay, to eat.
They make their own hay here, and before coming here I didn't really get what hay actually is.
Hay is summer meadows. Mown and baled and stored in the haybarn. (That I want to put a big rope swing in...)
And the cows and goats eat it and turn it into milk.
