Vindictive?

Out of all the animals, Fiona loves the goats the most. However, I'm wondering what her fascination is by leaving them a cow pattie daily in their pen. It's not vindictive, is it?

All we seem to do with this ongoing heat, is transfer the piles of poop in small stages. At night, we throw all the poop out of the barn and into the main pen. Then we later shuffle that pile into a bigger pile away from everyone and every thing. Eventually, that pile will be mixed with compost once the nitrogen has burned off enough. Then what? We're not sure yet. Our small pitiful garden doesn't need the amounts my animals are providing. 

For now, we're just happy all the animals are healthy. Soon enough, we'll be able to spend more time with them without us all melting.
