"Saparate pens for each animal, but they can share walls. More efficient that way. I'll go fetch more animals while you build?"

Sable nods and gets to work. Early in the process of deciding the layout, she has a moment of feeling like it would be easier if she could mark where she wanted walls and corners, and then a thought occurs to her.

"Oh hmm. We've got all this calcite... I wonder."

She crafts two calcite together... and gets a stick of chalk.

"We have chalk!"

"Oh, nice! That'll make caving a lot safer."

Hazel goes off and starts collecting the sheep she saw earlier. 

Sable chalks out the outline and carefully builds each pen, long rectangles sharing walls, with gates at the south (house-facing) end. Eventually they're all laid out, and she tries another idea.

Hmm. What if I try a recipe like the composter but shorter? That should be a trough, if we have that mod. Only one way to find out.

She tries it, and successfully makes a feeding trough. Then makes three more, and puts one in each pen at the front corner, for easy access.

Hazel goes and fetches cows, and comes back.

At which point she witnesses the sheep making a break for it over the fence by using the feeding troughs as steps. 

"Sable, they're getting away!"

"Shit! I should've realized the trough would be enough of a step."

She immediately picks up all the troughs and grabs a carrot and a stalk of wheat, and starts luring animals back into pens, and using fences to try to sort them back into the right pens.

Hazel helps out as best she can with her own wheat and carrots, and after a few false starts (and some interfering cows) manage to get the farmyard animals sorted out into a pen each. 

"Okay," she says after all the higgledy-piggledy is done with. "I think we have that sorted now."

Hazel takes a sigh of relief. 

Feeling a bit annoyed at the animals, Hazel heads downstairs to prepare to harvest them, primarily by making a proper knife to slaughter them with but also by arranging her food situation.
