We had a rooster we culled about two months ago, but my hens are still producing fertile eggs. I have an austrolorp that is about 17 weeks old, and I can't peg the gender of this one. My question is, seeing the still fertile eggs, could they be from my old roo? Or it this a sign my questionable gender austro is in fact a cockerel? The other day I did see "him" grab the neck feathers of one of my older hens, but it wasnt trying to mount, just holding the feathers... Opinions? I'm leaning toward Austro being a cockerel.
