so ´sheep´ here is singular?

[va-diim]

No, it's accusative plural, same as nominative plural. Accusative singular would be velkou ovci

[vD91V]

what about 'we are finding....'...is that not closer than 'looking for'?

[BoneheadBass]

Hledát means "to look for." "To find" is a completely different verb, najít.
