males and females of same age developing at different rates?

[QChickieMama]

I have 20 new chickens hatched 3/15/25, 3 males, 17 females. The roosters came of age and crowed a few weeks ago. However, the females in the same pen are not ready to be mounted. They're looking like adults but they're still pullets. Is this normal? I'm curious. The males were so aggressive they've been removed.

They were fighting each other--of course, and when I removed 2 of the males, the last one was chasing his favorite female all over the lawn, and not allowing the females to eat/drink on the ground. He kept fussing at them to move them up to the roost. Is this weird?

It is normal for the cockerel to sexually mature before the pullets. Normally the adult roosters in a flock will keep them under control somewhat. Good thing you removed them. They can cause a lot of stress on pullets.
