alt Hacker NewsI was speaking from the perspective of the people in my opening sentence. How commonly known would you suspect those facts are in your comment?
e.g. "[They might assume] cows simply produce milk like chickens lay eggs."
It's normal to never really think about it -- our society is set up so that you never have to. The secretion comes in a jug, the meat comes in cellophane, and that's it.

You may have a point that many have no idea how chickens work. Egg laying being like giving birth isn't an unreasonable explanation if you had to come up with one on the spot while completely in the dark. But most understand how milk is produced because even if they've never seen a cattlebeast, they deal with milk-producing humans daily.
