I weighed her today, and she's 9.75 ounces at 29 days old. As a comparison, one of my RIR's is 7.75 ounces and one of my BO's is 8.75 ounces. I think a wyandotte would be closer to the RIR, if not lighter, if I remember my last SLW chick. Probably doesn't mean a lot, but I was right, she is definitely heavier than the others.
