I rotate between the two hay racks. Whatever is left on the third floor (if there is any) gets tossed out. Then I fill the third level ring with whatever is in the first floor hay rack (sometimes adding a bit of fresh stuff, if it's nearly empty). I finish by adding fresh hay to the first floor rack.
The funny thing is, Boadicea waits on the third floor for the leftover hay. I guess being able to jump into the hay is more appealing than working the fresh stuff out of the downstairs rack.
Wedgwood gets excited, too. The first part of the video, she's lurking waiting for the bottom rack to be refilled. The second part, she can't make up her mind if she wants to wait for the bottom rack to be filled, or to go upstairs and oust Boadicea for third-level hay.
Yay for hay!
