Will males only have sperm plugs after you have started to cool them? I have 3 males that I hope to breed this year, but have not yet started cooling as they are a bit on the smaller side, in the 550 - 650 gram range, and my females are 1250, 1450 and 1900.

So far, no sperm plugs, but as I said, I have not started cooling yet as I wanted to put a bit more wieght on them first, all are still eating great as well as the femals... Thanks
