Plural of Sheep
“Sheep” is an invariant noun: one animal is “a sheep,” and more than one are “sheep.” Number is shown by determiners, quantities, context, and verb agreement rather than by changing the noun to “sheeps.” Do not generalize this zero-plural pattern to animal nouns generally.
The plural of “sheep” is “sheep”: the singular and plural forms are identical.

Quick tests
Plural-choice test
Are you referring to more than one animal?
If yes: Use “sheep,” with plural context/agreement.
If no: Use “a sheep” or another singular construction.
Caveat: Because the noun does not change form, agreement and quantity words carry much of the number information.
Examples
One sheep is standing by the gate.
Singular number is shown by “one” and singular agreement.
Several sheep are grazing nearby.
Plural number keeps the same noun form.
The farmer counted twenty sheep.
A quantity greater than one still uses “sheep.”
