Wyo. Stat. § 1-17-311
When an officer levies an execution upon any goods and chattels which afterwards remain unsold for any reasonable cause, the officer may for his own security, take a bond from the defendant, with security he deems sufficient to the effect that the property shall be delivered to the officer holding the execution for the sale of same at the time and place appointed by the officer, either by notice given in writing to the defendant in execution or by advertisement printed in a newspaper published in the county, naming the day and place of sale. If the defendant fails to deliver the goods and chattels at the time and place mentioned in the notice or to pay to the officer holding the execution the full value of the goods and chattels or the amount of the debt and costs, the bond shall be considered broken and may be proceeded on as in other cases.
