I have a 4 month old rooster he doesn’t crow yet or have spurs yet and he is with one hen. I decided to crack an egg open and see what’s inside and I’m just wondering if it’s fertile or not
To my Old Eyes, it looks like a Faint Ring around the Dot. I'd say Maybe. But I would let younger eyes confirm...JJ
Not fertile. And I wouldn't incubate any eggs from a rooster until at least 6 months of age. 1 year is better.
I have old eyes too and even have trouble determining fertility of my eggs with a magnifying glass. But I don't see a halo.
To me I can see a faint ring around it, I cracked some from my Bantams eggs that didn't have a very visible ring and put some in the incubator. They hatched regardless of that so were definitely fertile. If you are wanting to hatch some I wouldn't say there is any reason why you couldn't give these eggs a go. Then you'll find your answer as to if they definitely are fertile or not if some development starts. If no development starts then there's a high chance they were never fertile and you know to wait till your Cockerel matures. I do usually wait till my boys are matured/fully grown before I start hatching eggs from them but even then, sometimes you can end up with infertile eggs.
