Has anyone had DNA sexing be wrong? Pullet with large peacomb

I figured I may get further telling signs in the days between getting the second sample results back. The saddle feathers are opening up sort of in-between pointy and rounded, but they are thinner than anything I can find on a hen.

But more interestingly, I just watched "her" try to mount my biggest hen, an 8.5lb BCM 3 times...which is hilarious because he's maybe 1/5 of her size and just tumbled off... and then proceed to zoom around the pen challenging the other cockerels repeatedly. I think the male hormone switch has been undeniably flipped

So I have the results back. Confirmed cockerel. I'm okay with it because there has also been a pretty noticeable personality change with the physical changes. Poor guy is just kind of the odd one out now in the flock too.

I was pretty sure of his first DNA sample that came back female being clean and free of contamination on my part at collection, so I am not sure what happened, but I do know from now on with any more DNA sexing I will be doing blood only. Much easier to ensure a clean sample. It makes sense the feathers could have been contaminated since he lives with mostly girls.
