August 9, 2023 -

Each of the horses has their own food formula, which is carefully worked out by a dietician.

Why is their in this sentence incorrect? Probably just missing something easy.

"Their" is not incorrect there, because "their" can be used to refer to a single person/animal of unknown/irrelevant gender. However, some style guides/tests/teachers do not accept the use of singular "they" and the associated forms (even though they've been in use for almost 700 years). Whoever is saying "their" is incorrect there will want you to use "its" (one of the 3rd person singular possessives): "Each of the horses has its own food formula." Although "each of" is always followed by a plural noun phrase, it generally takes a singular verb form (note "has") and singular pronouns. However, as mentioned, it is perfectly acceptable to use "they/them/their/theirs" as singular pronouns: https://blogs.illinois.edu/view/25/677177 The use of singular "they" to refer to a person who uses gender-neutral pronouns is more recent, but no less correct.

So, I think the point here is that "Each of the horses" is a singular subject - the subject is the singular "each," not the plural "horses." But the sentence is fine & correct in colloquial English because "they" is the standard third-person pronoun when you don't know the gender of a person (or animal). I would guess they want you to say "its" instead of "their" to indicate the singular form. But generally in English we call animals he or she, not "it," especially if the animal is a pet or companion.

What do the pronouns 'they/them' mean?
They/them means the person prefers you to refer to them with gender-neutral pronouns. So instead of saying something like "She's on her way, we expect she will arrive soon for her appointment" it would be "They're on their way, we expect they will arrive soon for their appointment". Combinations like she/they or he/they mean that either the gendered pronoun or gender-neutral pronoun are acceptable. In either case it may be because the person identifies as nonbinary; neither a man nor a woman. In the latter case where they accept a gendered pronoun it would be up to the individual whether they're truly neutral between the two, or if they prefer one but tolerate the other.
