I got two Gold Stars in this year's batch of chicks - one was TINY and has continued to be smaller than the other Gold Star and most of the other chicks, but she seems to be doing pretty well. I don't know what she'll be like when she's an adult, whether she'll be smaller or not. I also got three EEs, and although they were all the same size at first (I thought), one of them is now smaller than the others. He doesn't seem sickly, but he's often off away from the others when the bigger chicks rush to eat at mealtime.
