When someone types 'sheep' into the tags, 99% of the time they're gonna mean domestic sheep. Similar aliases for other domestic animals have long been in place here (dog -> domestic dog, cat -> domestic cat, pig -> domestic pig), and the 'sheep' page on Wikipedia is the article for domestic sheep (https://en.wikipedia.org/wiki/Sheep )
Redefining sheep to domestic sheep also opens up ovine as a tag for sheep-like fictional species, such as Wooloo or Flaaffy.

In regards to the implementation of the sheep -> domestic_sheep alias, there are two options:
A. mass update sheep -> ovine beforehand, and leave ~26k posts that would need to be retagged with domestic sheep.
B. just let the alias go through, and have domestic sheep incorrectly affixed to ~1.9k posts from which it would need to be removed.
I think option A is the better one as the retagging could be scripted pretty easily (add domestic_sheep to ovine -argali -bighorn_sheep -dall_sheep -mouflon -snow_sheep -urial -pokemon)
