Somewhere in my files I have a photo of 3 Mastiffs, a couple of cats, 4 chickens and chicks, and a crow, all drinking goat milk out of the same pan.I always fed excess milk and whey to all my critters. Great stuff !What's your opinion of cultured buttermilk? My does are dry now but often, when I'm feeling lazy, I mix Layina, fish meal and enough goat-buttermilk to make a very dry mash. The chickens love it. I sometimes use whey as a substitution.
