Perplexed. Silkie bearded vs non bearded

[ronkonkoma]

I got this baby in the middle from a very reputable breeder. I asked for bearded only eggs. They all have beards except this guy.

Let me ask so I know for the future
Bearded x bearded = full beard
Bearded x non bearded = tiny beard?
Non x non = non

Am I right?? Haha. So confused. Can you have a non bearded chick pop up from an only bearded pen? Is there a chart for this

Bearded x non-bearded makes for partially bearded offspring.

Bearded x non-bearded makes for partially bearded offspring.

I suspect the breeder may have had some partially bearded offspring in his bearded pens, probably due to the varieties being mixed in the past.
