    1 year - they are pullets and cockerels until then.

    Yeah...one year in general, although mine seemed to have stopped filling out by 9 months or so. Now really big breeds like JGs and such probably take longer...

    Depends on the breed. A year is when they become hens (from pullets) and roosters or cocks (from cockerels). Some of the giant breeds take longer to finish growing. My LF brahmas were close to two years old before I noticed that they had stopped growing.
