title: Netlogo - how to count turtles number around a specific turtle
body: <p>I need to "do-something-special" if around yellow turtle there is at least 3 blue turtles . Is the code bellow correct?
  I tried</p>
  
  <pre><code>ask turtles with [color = yellow]
    [
    if count turtles in-radius 1 with [color = blue] &gt;= 3
    [do-something-special]
  ]
  </code></pre>
  
  <p><code>do-something-special</code> should remove (disappear) 3 of blue turtles and current yellow one</p>
  
  <p>Did I do the location of relevant turtles correctly and how do I kill them after I find them?</p>
