Hi haTHOR
POL (point of laying) humm... honestly it depends on when the pullet hatched, fall, winter, spring, summer and what the weather conditions are light wise and what they are eating. I know that sounds vague, sorry. If conditions are normal: early spring hatch lots of fresh air, growing room, no older hen picking on her, nest box ready, she will start to lay late fall but I have also seen them wait till the following spring. Some Javas are late bloomers, some early, just watch the girls when you see the combs and wattles start to pinkin up and the ear lobes too, they are getting ready to lay, also an older Java rooster knows. He will not really pay any attention to younger pullets (as long as he has mature hens with him too) until they are close to laying. But watch the hens they love to put younger pullets in their place. Don't count on a younger rooster, you know they like to jump anything just for the practice, but again that is not always true either.
I have seen where a young rooster was raise with the pullets and his first instincts are protection then when the girls are ready to start laying he becomes a Romeo. I often wondered if it was a change in how the female smells to the male???
I have seen where two rooster raised together work the flock together. One will stand guard, the other will walk with the girls and eat and later they will switch places. When the one standing guard makes a certain call sound they all go for cover or just get very still and squat down. If you look up you will see the air predator the first guy was fussing about or ground predator.
I have seen a Java rooster use himself as a target for the predator, running away from the hens with the predator chasing him to save his girls.
LOL my youngest son tells people to not get me started talking chicken.
My thoughts: just watch them and they will tell you when they are ready.
