feeding port
also called feed/water access
Through what access-station structure an animal takes the ration a vessel presents — a token from FeedingPorts (gravity feed pan, open feed tray, vacuum water trough, water nipple). The exclusive differentia of the poultry feeder/drinker kind: it is what makes a feeder or drinker husbandry equipment rather than a plain vessel (it PRESENTS its contents for continuous animal access, rather than storing them). DISTINCT from the closure family (lid_type / sealing / lid_mechanism / latch — which govern retaining or opening a vessel's stored contents for a human), from spray_mechanism (pressurize-and-atomize on discharge), and from drainage (a planter's base water outflow). A category discriminator (a jar feeder, a bell drinker and a nipple drinker are different products/listings, never within-model buy-box versions of one another), so grouped_in identity and non-axis-eligible.
Feeding port is answered with one word chosen from the feeding ports list — the same word shared across every product that uses it.
It belongs to identity — who and what it is.
