What will they eat?

Hi, all
We purchased property last year and are beginning to add our livestock. We are going to pick up our goats in a week or two. They are a hybrid of Pico, Boer, and dairy goats. We are using them for brush clearers/pasture pets:)

Anyway, the previous property owner placed water tanks at the top of the property. In the pasture we are planning to use, there is above-ground piping that leads up to the tanks. It's the black K-Flex piping. My question is: will the goats eat through that? We don't need those water tanks yet and can definitely remove/replace the piping if necessary.

Thank you all for your insight!

The only thing I can say is that I've never had my goats or sheep chew on my piping, which is also above ground.
