Livestock population in Town Storage not shown in Trading Post

When using the trading post, livestock (Horses, Cows, Goats, & Chickens) always show 0 population in Town Storage.
I think it’d be nice if it showed total population of each, so we can select the number to sell.
As I’ve never seen a single merchant that is buying livestock, I believe a separate livestock auction might be a cool addition, if this population count is too hard to implement.

This is not a bug. Livestock is never stored in town and cannot be traded.
