Not much but you have to try not to over feed them. I know they run to the cage like maniacs and it seems like they're hungry. But probably they like to eat a lot. And also remember giving them a lot(TRUST ME! A Lot) of water.
something to say you can have a pet duck.
i assume you mean a pet dog... they will eat around 2 raw meats a day OR 3 bones a day. if you are wanting them to grow fast, food will not affect them, it is how much you walk them.... good luck
Put a cup full of food in and they'll eat it when they want to
can you stroke a duck as a pet without it damageing its waterproofing .
of course they are! I had a pet duck once. I named her aPirl
dog duck (weird pet) dove ^^
you have to buy it in the pet shop (:
It depends on where you live.
Dog food tells you on the label how much to feed your pet according to their weight.
