Hummingbird Poor Score because Remove render blocking resources

Hummingbird gave me only 18/100 for Remove render blocking resources. This is what it's suggesting:

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

All those are coming from Hummingbird CDN.

How can I increase the score? I've moved assets to footer as far as possible without breaking the site.

    Hey there Jeffrey Euen-Gow,

    hope you're doing good and please excuse our late reply here.

    It seems that these assets should be loaded in order for the above-the-fold content of your homepage to be displayed.

    This can be surpassed by pushing assets to footer indeed.

    If you find yourself struggling with this, and can't find any other asset that could be pushed to footer without breaking things, you may try to exclude the "combination" switches ("merge with other files"), so they could be less assets being loaded for the above-the-fold content.

    This doesn't ensure that the score will increase though, you should first have in mind to keep WP, plugins and theme working effectively.

    Hope that was some help, let us know if further assistance is required here!
    Warm regards,
    Dimitris
