Enable for featured images of posts on home page?

I am using the Genesis framework and the home page of my site lists the blog posts including their featured image. It doesn’t look like lazy load is working for these because the images don’t have any of the lazy loading properties in the HTML. Any ideas?

Here is my URL: https://iowacru.com
