Exclude a specific post in a Custom Post Type

I have a very simple query to display all my posts in a custom post type:

<?php     $  page = get_page_by_title('Duck');     $  args = array(         'post_type' => 'sessions',         'post__not_in' => array($  page->ID)     );     $  query = new WP_Query( $  args ); ?>  <?php if ( $  query->have_posts() ) { ?>     <ul>         <?php while ( $  query->have_posts() ) { $  query->the_post(); ?>             <li>                 <?php the_title(); ?>                 <?php the_content(); ?>             </li>         <?php } ?>     </ul> <?php } ?>  <?php wp_reset_postdata(); ?> 

What I want to do is display all the posts except the "Duck" post, I’m getting it’s ID by it’s name – which normally isn’t a problem, but the query still shows this post. I’m guessing I’m just not going about this the right way.

Can anyone help me out here, I was also thinking exclude > $ page->IDor something like that – which is what I’d do in a regular loop…just not sure how to do it in a Custom Post Type.
