How many weeks till Mr.Roo will fertilize the eggs

[corochic]

Hi My Rooster is now 22 weeks old, he is enormous and I want to put him with a couple of hens. Is he old enough to know what to do and will the eggs be fertile. Looking forward to some helpful answers.

He should be sufficiently old, but I'd suggest observing him, to make sure he is "doing his thing". The hens may not take too kindly to his clumsy advances in the beginning - hence you need to watch him.

After a few days of what you see to be successful matings, you can check the fertility of the eggs, by cracking one open and observing the yolk. These links should help
