The claim specifies details (500 ducks, April 14, Howard Berkowitz, Orange County Register) that are not independently corroborated by the provided web search results. The evidence provided for this claim is general information about Riverside County or unrelated topics, not confirmation of the specific event reported by the OC Register.

One web search result states that 'All adoption fees were waived, and the ducks were made available at the San Jacinto Valley Animal Campus beginning April 15.' This supports the core elements of the claim, but no second independent source confirms the 'first-come, first-served' aspect or the specific details across multiple outlets.

The web search results mention that 'Some ducks reportedly had zoonotic diseases' and that there were 'accusations that the animal agency released animals without proper disclosure.' While the concept of zoonotic diseases is discussed generally, the specific accusation linked to the agency's release of ducks is only presented in the context of the search results, lacking a second independent source confirming this specific accusation.
