Ah . . . Vertical Farming

While Athena was explaining the other features of the animal pen, instead of listening, I was busy arguing with the system. 

"The feed storage room is customized to prevent moisture. Most livestock can eat hay, silage, legumes, and grains. Birds feed on birch branches and nestle leaves in summer, which saves them from vitamin deficiency and allows them to fly faster in winter.

"A mud pit is necessary for any hog farm. Pigs don't have sweat glands, so they need to wallow in mud to regulate their body temperature effectively. 

"Chickens need an ash pit to clean their skin and feathers from parasites. Make sure that the ratio is one part ash, two parts river sand, and 100 grams of sulphur — because concentrated ash contains potassium and soda that can irritate the skin and mucous membranes of birds.

"I'll have Ulysses make one later."

"Is that so?" was all I could reply with. I didn't even understand most of what she said.
