I have also, but trimming did not help, and AE did not work, the only thing that worked was getting a completely different line of Biel males.
I am gonna guess, there is an inbreeding infertile issue here, my males were acting male, and fledging male...and they were upset when I took them away from the females and placed them on the other side of the fence....after a week, put them back and they just sat, and sorta acted like hens.
They had no desire to mate, not one actually mounted, and no amount of cushion trimming would work...and seriously, we had 4 males & tried AE...and there was no joice !
I never did a necropsy on these males to see if maybe the testes were shrunkin or ?????
Like I said, I have gotten over 5 lines of Biels now, and it is working like magic !!!
Thanks for the info! Did you ever get fertile eggs from your male? Is it even possible for a Rooster to be fertile his first month or so of breeding and then become infertile the next month - due to inbreeding? During the months of December and January I did witness the rooster mating - very aggressively. And I was getting eggs from the three hens that were ALL fertilized in January. Based on what I'm reading throughout this thread I think perhaps he has simply stopped mating for some reason. An unknown reason that is not impacting any of my other breeds. I will try to watch this weekend to see if he's still even attempting to mate. But he was absolutely fertile a month ago. Again could the inbreeding issue even be an issue if he WAS fertilizing eggs when he first came of age to do so?
