There is an easiest way to crop an image : 

$picture = new Imagick('animated_gif.gif');

foreach($picture as $frame){
    $frame->cropImage($width, $height, $x, $y);
}

If you're working with animated gif you might want to process this way (Probably not the best, but at least it works) :

$picture = new Imagick('animated_gif.gif');

//Crop first image
$picture->cropImage($width, $height, $x, $y);

//Crop every other image
while($picture->hasNextImage()){
    $this->nextImage();
    $this->cropImage($width, $height, $x, $y);
}

//display image
$picture->getImageBlob();
