Ooohhh… I might need to learn how to do this and see if my girls like it. I often drizzle a bit if store bought goat milk kefir on my dog’s kibble.Yes I do make it myself.
I make it in a mason jar on the counter-top - or in the fridge if I need it to slow down. I am quite a fan because I like those sorts of sour flavors but I know not everyone likes it.
Before I figured out the ladies liked it I was wasting a lot of milk because the little kefir grains are rather productive and were way outpacing my ability to eat it but you have to keep feeding them anyway.
Turns out the chickens love it and if I freeze it before giving it to them then they make less of a mess than if it is liquid. It is also a good way to slip in extra calcium (I add some powdered calcium to the pot before putting it in the freezer) and I often throw in kitchen scraps as well.
