What is normal for a 6 month old pullet as far as weight?

[Paully3]

I have several young pullets of different breeds and they eat fine and are very active, but I have noticed that when holding them, I can clearly feel their breast bone. I have read that this is a bad thing and I was wondering if it is normal at this age, that maybe they just haven't filled out yet? Several are showing interest in the nesting boxes and 1 has laid a cute little pullet egg the last three days.

Different breeds weight different amounts. Small breeds may weigh 4 -5 lb and larger breeds may average 6, 7, 8 lbs for hens and more for roosters. They need at least 16 % protein in the diet of a well balanced layer or all flock feed. I feed a 20% all flock with crushed oyster shell for their free choice of extra calcium. Worms, coccidiosis, and other problems can affect their weight.

We feed a 16% layer crumble with free choice calcium and grit scattered through the pen.  We also supplement with mealworms and are going to be doing fodder soon.  I was wondering if it is normal for chickens that are still growing to be slim, not filled out yet...Also...we have a quarantine coop that had a bird that tested positive for worms so the vet gave us enough Panacur to do our entire flock. So everyone has been wormed 1 week ago.

I have no idea how accurate this is:
