All sources I consulted agreed that multiple possessives of the deer should be written in apostrophes before the -s, as in this example.
Which is the correct plural possessive?
The general rule is that possessives of singular nouns are formed by adding apostrophes and s, regardless of whether the singular noun ends with s. Plural possessives are formed by adding only apostrophes if the noun ends in s, and adding both apostrophes and s if the noun ends in a character other than s.
What is the plural possessive of an animal?
Plural nouns use an apostrophe after the last -s. "Animal" means to belong to multiple animals, and "eerie crawl" means to belong to multiple eerie animals. Greek names ending in -es, pronounced "-eez", like Socrates, form possessive in the last apostrophe, Socrates.
