I also had issues with fertility but it was not my Rooster. He did well with all the other hens. It was recommended to me that they may need a higher protein content. I increased their protein and I was able to hatch out about 3 babies. They are wonderful birds but I didn't have the time I needed for serious breeding, which they so desperately need and in my opinion are worth saving. They just have a LONG way to go to get back to the sustainability dual purpose bird that they were.
