I have a awesome rooster. He's friendly, not aggressive to us [he'll come hop in your lap if you've got bread!] and he takes good care of the girls. He's been "mounting" our cochin, who wasn't laying eggs up until yesterday....but I've gotten an egg yesterday and an egg today from her. She's my only bantam so it's easy to tell they are hers! They're only half the size of my Orp eggs. I, of course, opened her first egg yesterday to see if it was fertile. It wasn't. So I'm curious. Since the rooster is obviously 'getting his hump on' how long will it take for the eggs to be fertile? The rooster has been mounting her since last week. I didn't know if it would take a couple days for the eggs to become fertile once she started laying or what? Can anyone advise?
