Explaining Search Error and Topsoil Building

What happens here

The farmer clarifies the 'boo-boo' he made when searching for Cindy's calf. He explains that when he walked up on the calf, it bolted and ran almost a mile into the woods, eventually laying down. He had previously searched that area on foot but only found it the next morning with the drone. He then reiterates his method of feeding hay to build topsoil, explaining that it helps replenish nutrients and organic matter in the ground. He also introduces Tammy, the farm's guardian donkey, who keeps watch over the babies.

Goal: Detail the farmer's error in a past calf search and explain the topsoil building process.
