I've found that when hypos are hatchlings is when the difference is the greatest between them and normals. So if you look closely at one of the ones you think is amel, you'll see its a little darker than the other amel and its eyes aren't that orange/pink color, but darker. The saddles are also surrounded by a really washed out grey color and aren't totally white like the amel. Have a closer look, and hopefully you can see the differences.
