I've been wondering the same thing. Mine have been laying for several weeks(the younger ones only a couple of weeks, and not all of them yet), but the largest my egg scale measures them at is between small and med. Many don't even budge the scale yet, so they are "pee wee"! These are from SSs, SLWs, BOs, and Lt. Brahmas. I guess we just have to hang in there and wait.
