What kind of goslings are these?

I'd guess Hatchery African which is basically a cross with an African and a Brown Chinese.

Chinese are smaller, and the browns are supposed to be smaller than the whites, so they're a pretty small goose. Chinese are very loud, and somewhat aggressive. Africans should have a dewlap. Africans have a thicker neck. (I've seen white Chinese marketed as "the goose that looks like a swan).

Africans are bigger than Chinese.

Yes. They probably won't have a dewlap, but they should be a little bigger than the Chinese.

If they do have a dewlap, they're definitely Africans. If not, they're Chinese, or African hybrids.

Thanks so much for the info!
