Drinkers. . . never never
the sweet plastic ones for hens if all else fails a washing up
bowl with a brick works. Just work out how much they drink the
fact that their beak does not fit in efficiently and how many
times you will have to refill it

Useless for all except tinies... works for babies but not UV
safe goes brittle if outdoors

Again okay for babies adults beak does not fit unless you can
find the large yellow goose one on alibaba.com
Food Bowls . . . At present I
am using plastic Ikea dog bowls on a block wired to the fence
through that nice little hole at the side. . cheap
simple a few of those means they all have a space to eat and
any ill not eating are obvious. Ducks and gees both prefer
food not at floor level so even old free plastic bread trays
or plastic veg crates upended make a good 'table' anything
falling though is then hoovered up by wildlife and no rat
holes hiding under trays!
Below all recycled customised options. . . .that will work
Plastic tub+ drill+ bowl beneath

Guttering + wood top cover helps in wet weather
Option for tinies esp Muscovies I would use a water
trough after 2 weeks as easier to refill. . . keeps them
dry/clean etc
Outdoor food station not hard standing next to water to
prevent mud central

Bucket hopper can also be bought ready done
Off the floor for calls etc stops waste
The simplest add scissors or knife to plastic container
use anything from cable ties to hooks to attach. I use Ikea
hanging kitchen hooks or wire on to the fence
Hardstanding blocks/ paving slabs/ wood where they eat
prevents mess and shows up if you get a rat hole but do lift
them off the floor as ducks / geese do NOT eat like cats
