Open index.php in your theme folder
replace with the_content() with the_excerpt() function
of course in the settings -> reading i have setup full text
this only works for RSS feeds, not for the content n the blog.
review http://codex.wordpress.org/Function_Reference/the_excerpt
for theme specific support, please post in https://wordpress.org/support/theme/blackbird/
The problem is that i do not have the functions, below my index.php in my theme folder:
<?php
/**
* The main template file.
*
* This is the most generic template file in a WordPress theme
* and one of the two required files for a theme (the other being style.css).
* It is used to display a page when nothing more specific matches a query.
* E.g., it puts together the home page when no home.php file exists.
* Learn more: http://codex.wordpress.org/Template_Hierarchy

<?php get_footer(); ?>
this line
<?php get_template_part('loop', 'index'); ?>
points to loop.php
check the code there.
Done, sorry but i do not know php, i am a java programmer 😉
