Generally speaking, Zone 1 is the area immediately surrounding the house - where the things you do every day are.
Like garage/car port, work shop, kid's swing set, herb & kitchen gardens, BBQ, grape arbor w/ picnic table, etc.
Since hens need to be serviced every day, ie collecting eggs, feeding scraps/garden waste, 'lock-down' at dusk, etc it stands to reason that they belong in zone 1 (or at the edge between Z 1 & 2). You carry garden scraps on the way there, and eggs on the way home.
In my mind, a dairy cow w/calf falls into that same 'daily care' category. You don't want to be lugging pails of milk 400 yards every day. Perhaps, with the milking parlor being the border between zones 1 & 2.
If it was beef cattle, I'd say anywhere except zone 1 or 5.
