Colo. Rev. Stat. § 35-46-103
When any person is trespassed upon or damaged by any livestock or takes into his custody any livestock under section 35-46-102, the claim for damages occasioned by said livestock may be arbitrated by a board of three arbitrators, at the option of the party aggrieved selecting one, the owner of the livestock selecting a second, and the two thus chosen selecting a third. Said arbitrators so chosen shall meet and act as a board of arbitration within five days after a written application is made therefor by either party and written notice given to the other party. It is the duty of the person so taking into custody such livestock to notify in writing within five days after the taking into custody thereof the owner or person in charge of such livestock. If the owner or person in charge of such livestock is not known to the person taking the livestock into custody or cannot be found after diligent search and inquiry, then the person so taking custody of such livestock shall publish within one week a notice containing a full description of such livestock, including all marks and brands as nearly as can be ascertained, in a paper published nearest the place where the alleged damage occurred. In the event the owner of such livestock cannot be found within ten days after the date of the publication of such notice, the livestock shall be an estray and the state board of stock inspection commissioners shall be entitled to said livestock subject to the lien for damage sustained and cost and care and feeding of the same by the person taking such livestock into custody. Such person shall deliver the same to the owner thereof whenever such owner furnishes the person so damaged by such livestock a bond in double the amount of the damage claimed, executed by two responsible persons, said bond to be satisfactory to such damaged party or approved by a county judge or district judge of such county, conditioned upon the payment to the person taking custody of such livestock all damages and costs, if any such damages or costs are awarded.
