Your goats keep getting out to eat your bushes because the bushes are healthy for them. The bushes are green, therefore they are healthy for them and your goats know it. Dogs do the same thing. They will always try to eat the grass because it's good for their health. The bushes are their vegetables so please let them eat them.
I’d love to hear recommendations too! I really like Kicking Horse organic whole beans Swiss water decaf, which is dark roast. I also recently tried Bulletproof Swiss water original decaf whole beans (a medium roast, and it’s tested for Mycotoxins) and it’s a good basic flavor. I’ve also used both Mayorga organic Swiss water decafs in the past. I enjoy the Kicking Horse decaf taste better than the others, but always trying something new!
