Limiting number of eggs and hatchlings

[SilverDragonTears]

Currently I have this which says if you have more than 5 eggs you can't adopt.

$stmt = $adopts->query("SELECT * FROM ".constant("PREFIX")."owned_adoptables WHERE owner='".$loggedinname."' AND currentlevel<='3' AND isfrozen='no'");
$data = $stmt->fetchAll();
$num = count($data);

if($num >= 5){ 
$canadopt = "no"; 
$article_title = "Too many eggs!"; $article_content = "You already have too many eggs to take care of! Come back once you have hatched an egg!"; 
}

How can I change this so that you can't have more than 5 eggs AND say... 10 hatchilings at a time?

this is brilliant, which program did you insert this code to, and what line? I'd be happy with just the limiting eggs.
