As a native San Diegan, the San Diego County Fair has been a must do part of my summer for years!

The livestock at the fair gets rotated, so you might have been there on a day when they were rotating them out. I know the week I went there were chickens and goats and cows in prominence. My friend went the next week and saw rabbits, guniea pigs, and pidgeons so the livestock they have depends on the week you go.
