Please Help - Baby Chick May Be Sick

[ChipandDip]

Hi, I have two baby chicks currently, which I got at separate locations and times. One is a month old Silkie Bantam, and the other is a Black Australorp.
The Black Australorp is about a week or so old. And he starting pooping out what appeared to be worms to me. I called the pet store I bought him at, and they told me I could exchange birds, since he is too young for me to deworm him with their products. But I am very attached to him now and I cannot do it. I want to be sure that what he has is worms. Attached are pictures of his stool below. Please help if you can!

Best to post in the disease forum. Are you just going off of the droppings, or are they acting sick. Poop color and consistency is usually based on their diet. Your chicks are pretty young to have a worm problem, so that wouldn't be my first thought.
