Okay, my chicks are all 3 weeks old. I'm starting to be concerned that one of my delawares is a roo-let. The first picture is the suspect, the second is a picture of the suspect with the other same age delaware. The suspect chick is bigger, has thick legs and acts much bolder. The last picture is an Easter Egger that is also bigger and bolder than the rest, but I'm pretty sure it is too early to tell for this one.
