I got my chicks when they were two days old. They are splash orpingtons. As you can see, the one on the right is very small. She seems to be the same size as when we got them, about one month ago. She eats, drinks, and acts normal. As a matter of fact, I have seen her walk on top of the others when they are eating. She does not seem to be scared of much, but when she is, like when I took this picture and they all huddled together, she got underneath them, literally. Any thoughts?
