Crab apples?

[inputoutput]

I have a tree full of crab apples. Most haven't even dropped yet despite the tree having no leaves. Can the ducks / chickens eat these?

Our very young crabapple trees have some kind of berries on them. Are these the actual crabapples?

Yes, they can. They're just small apples.
