Geese are individualistic so some like some things while others will like something else, but they definitely do have their favorites.
Parsnip and Delphi are addicted to tortillas. Roxby likes them sometimes, the rest don’t have much interest.
Roxby, Apricot, Tuesday, Dandelion, and Helios love bananas, some of the others either don’t like them or are “meh” towards them. If one of the others gets between Roxby and his nanas there will be blood shed though.
Half the flock likes tomatoes, the others don’t.
Everyone loves blueberries except Tuesday and her mom Delphi.
Everyone except Parsnip, Leo, and Delphi like carrots and broccoli.
Sometimes everyone likes strawberries, sometimes they don’t. Plums are also a case by case situation.
Most of the geese like oranges and mandarins, Friday and Leo are obsessed with them.
Half the flock likes cabbage.
Romain lettuce, lettuce in general, grapes, cucumbers, corn, watermelon, cantaloupe, clover, and apples are loved by everyone, except my old gander Thor who thought apples were trash.
Everyone hates peas which I’ve heard is strange because everyone else’s geese love them.
Point is there’s lots of options to try, geese can take awhile to get used to something or be willing to try something new sometimes, if they see you handling or eating something they’re more willing to try it.
Things to avoid are things that for the most part you shouldn’t feed to dogs either, like onions, chocolate, avocado, and so on.
Another rule to abide by is if you wouldn’t eat it, they shouldn’t eat it, so nothing rotting or moldy.
