When does a rooster become fertile and start mating?

 

[Habibs Hens]

mine usually start at around that time and teh eggs are very very fertile as my fertility rate was 100%

It depends on the breed and the time it takes the roo to mature. I had a RIR X mate with one of my hens when he was around 5-6 months old. She went broody and none of her eggs were fertile. She hatched 3 doz of her own eggs before that with no problems. He's since been practising daily and he fathered lots of chicks.

My new frizzle roo is around 15 weeks and is producing 75% fertile eggsat the mo. I think It depends on the breed and bird.

I have Seramas and one of my little almost-12 week old cockerels is in a cage with a little pullet of the same age. He most definitely is trying, and he is in love with that girl. He talks to her, feeds her, worries if I take her out of the cage. Gah. Maybe putting them together already was a bad idea. He has a show to go to in January...I was not planning on taking her, but I might have to, to keep either of them from fretting too much.

I think it does depend on the breed/ bird...my Jersey Giant boy has been in with pullets all his life(2 are his sisters, the other 13 are 1 month younger) and he is 14 weeks and has not started crowing or trying anything with the girls...
