Hi everyone, I have not been around for a short while as I have been non-stop since returning to work from my medical leave. But I do try and check here as often as I can! I have a question, is there such a thing as a sterile rooster? I have had two broody's since spring, they both have sat on full clutches for the alloted days with no hatches. The eggs that do not break in the nest are just yolks, nothing formed at all. My rooster is on those girls all the time so I am just stumped! I am thinking it is possible that my big man is shooting blanks. Anyone ever have this problem?
