My 17 week old Black Australorp has been jumping on top of my girls. Is it possible that some of the eggs may be fertile? Should I let one of the hens who is showing signs of going broody lay on the clutch? Is there any way to tell?
check a few of the eggs for fertility, crack a couple open and look for an enlarged white spot on the yellow part of the yolk. If you can ppost a few pics of the spot, lottsa folks on here can help you determine if it looks fertile. I think your roo is probably fertile at his age, but I'm not a roo expert!
Of the ones I could see, the first didnt look fertile, but the one before the last one (the 3rd pic, I think) looked fetile to me. Even with a roo, I think it is possible that not all eggs will be fertile. But I think you have a soon to be daddy roo!
