OK , now I get a clearer picture of the situation. Your chicks will be confined to the area and will not need to be using the ramp for a certain amount of time. You will see as things progress how the chicks move about. They grow FAST. 
You may just need to place a small piece of carpet/rug over the lip for the first few days. Then they will have no problem getting in and out. In a few days you will notice they can jump higher than we can.
