My younger pullets are getting way bigger than my older girls

My 16 week old pullets seemed to have stopped growing (first three pics) I’m not sure of the breeds basically BYM. My two Oliver Eggers and BCM are 13 weeks and they surpassed them in size a few weeks ago. It’s wild to me how big they are getting so fast. Maybe the breeding was just better since the BYM came from my sons school hatch so they just aren’t as quality?

Any difference in the diets the were raised on?

The BYM from your son's school hatch might just have some bantam genes mixed in.

As long as they are not plagued by internal or external parasites that can stunt their growth, there is nothing to worry about.

No they’ve been raised on the same thing

I don’t see anything that leads me to think parasite. I thought my one girl was a bantam because she’s always been way smaller but there’s also a leg issue, so I think that’s why she’s not growing
