Goats eat. A lot. And with 5 of them, they can demolish a lot of greenery in a short period of time. Here’s an example – we have the goats on our west hill, which hasn’t been mowed or grazed for 5+ years, so it’s very grown over:
Enter the goats – this picture is after 5 days of goat demolition:
And after 7 or so days, here’s the carnage:
As you can see, there is a lot of thatch and dead grass, but after another year of goats working it over, this area will be looking much better and be growing better grass for the goats to eat!
And as to what greenery goats won’t eat – there is a type of low-growing ground cover (found especially under our pine trees) that they just don’t like.
