First calf heifers

Just curious what people expect from their first calf heifers when weaning calves in the fall? Do you still expect them to bring a calf in that is half their body weight?

I think it is really difficult to talk about weaning weights with clubby producers... they typically wean early and before that start creep

our calves are March borns and have already been weaned a month
I got them to the scales last week and the 2 bulls weighed 530avg... the remainder averaged about 420 with the first calvers being about 15% lighter than the others
we are going to sell them early october and I think they will average 520 by then
