Are you feeding them something different than you have in the past? Do you soak your chuck starter with water to make a cake like texture for a "meal" or two per day?Those are good weights... I'm of the school where you still want good feed conversion. It is interesting that in these modern times - even recipes are calibrated to use large eggs....So we are now having Large be the norm. I don't mind medium if they are daily... I will be happy with healthy hens at the light end of the continuum. Let's all have a major weigh-in in Januray of 2015 and see what the norms are.
For people who want to track their chick growth... there is a form to fill out on the Club's website. Once you enter the first weights you probably will need access to the spreadsheet.. it's a tool for those who want it. The chicks here - two from one totally different parents than the other one all weighed 1/2 pound at week 3. Can't believe how big they got that fast. And since they are not from the same parents it has to be the feed-- or maybe 1/2 pound at 3-weeks is normal.--- my others didn't seem that big that fast...but memory fades...fast.
