I tried breeding 3 boys last year. One was a bad feeder his whole life so it was no surprise that he stopped eating on me. He's an '09 and only 450 grams. He's a real pain in the rear...

Anyhow, other than him, the other two males didn't stop eating, but I keep my males on the small side and feed them small meals every 10-14 days during breeding season. It was advice I got from a breeder that seems to be working well. I'm doing it again this year, so we'll see what happens.
