Saruman likely started breeding them before Bilbo's party. It would take a long while to dig such caverns, and it is likely that it was done in secret, along with the breeding of the Uruks. Once Gandalf discovered Saruman's treachery he likely decided that his cover was blown and unearthed the caverns for greater ease of access, and also increased the amount of Uruks he was breeding.
