So when are they fully grown?

I didn't know where else to post this, so mods please feel free to move if need be.

When are regular standard breeds considered physically fully grown- at POL for each breed? I have EEs, Marans, and Black Stars. I know the BS will lay earlier than the other breeds, usually. I'm just curious as to when they'll be as big as they're going to get.

It depends on the breed, some are slower to develop than others. And it can also depend on environment, free-range birds tend to grow a little slower, ime, but catch up with their confined counterparts in time. With the exception of some of the really big, slow developing breeds -- like Brahmas -- however, I'd say most will be full sized by around 30 weeks old regardless of environment, earlier if they've been confined.
