Avocado...........
Citrus fruits can cause acid reflux and stomach pain in ducks. Mangoes can make ducks' throats itchy, as it does in some humans. ... If they seem fine and enjoy it, then it's okay to feed to them mangoes. All parts of the avocado plant, including the flesh, can be toxic to ducks. (i got this off google lol)
sorry for being a "party pooper" lol but its really bad for them....sorry
@Hybridchucks, thanks for the info! I had noo idea!
Luckily, they happen to be fine... I didn't feed avocado that often, only if I happened to remember to snitch some while eating a salad
They are snuffling next to me in the grass as I type
