Vt. Stat. tit. 30 § 3010
Unless the bylaws prescribe the presence of a greater percentage or greater number of members for a quorum, a quorum for the transaction of business at all meetings of the members of a cooperative having not more than 1,000 members, shall be 10 percent of all members, and of a cooperative having more than 1,000 members, shall be 100 members. For the purpose of determining the presence of a quorum under this section, all members shall be counted who are either present in person or who vote on business transacted at the meeting in a manner allowed under section 3011 of this title. If less than a quorum is present at a meeting, a majority of those present in person may adjourn the meeting from time to time without further notice but no business may validly be enacted at any meeting without the presence of a quorum.
