BLUE TONGUE SKINKS

I had my Northern out on my chest this morning and noticed he started to lift his tail so I plopped him onto a puppy training pad - saw full hemipenes evert and he dropped sperm plugs! For reference, he was born May 19th, 2021 so he should be 6 months old on the 19th of November. As of right now I'd say he's probably 5½ months old for simplicity's sake. I was absolutely floored - never thought I'd be that excited to see poop and lizard weiner! I haven't heard of it happening that early and I messaged the breeder and he says the only time he's ever seen hemipenes from males was after breeding, and certainly not this young. For breeders especially, what's the earliest you've seen hemipenes and/or sperm plugs?

Yes, it happens and not infrequently. I've seen as early as five months.

Yes my boy was around 6 months when he started (and never bloody stopped) passing sperm plugs
