Jackie brings her ewe flock to a new pasture and we see the ewes really going after a native plant called teaweed. Teaweed, native to south Mississippi, is high in protein and digestible nutrients. Teaweed is discussed further in the video and here is the citation and link to the source article describing the attributes of teaweed:

I watched for a few minutes, but gave up when there was no explanation about the elephant in the room, the things on the dogs necks.

Ah yes, the triangles. I think I explain later in the video. They are temporary devices to discourage tunneling under fences. Jackie took them off after a couple days after the dogs are familiar with the new area.
