I wasn't offended nor did I mean to offend, all I'm saying is that it is in fact, as you've said too, something that differs per experience which allows the formation of opinions based on the experience. I even mentioned at the end that it all comes down to strain, environment, and climate. I've known a lot of Polish that yes shouldn't be with larger breeds due to their behavioral differences, and some that are perfectly capable of flock mixing. I've worked both with mixed flocks and separated pens with Polish, Houdans, and the various other non-crested breeds out there.
My point was that behavior is not something you can count on with wondering what the difference is when it comes to crested breeds. Appearance and genetics are mainly it, since there's nothing in the standard nor what most breeders focus on, that asks for a specific behavior in Polish. All of my current Polish from various sources are perfectly capable of being in a mixed flock without being picked on, but so are all the Marans I've had, too. In fact any of my Marans are more laidback and passive than my Polish. It's a differing thing dependent on variables like strain and environment, but not something to rely on when comparing crested breeds. I myself never know if some Polish or Houdans I pick up are going to be skittish and flighty or not, as I've had some pretty spooky ones as well as some aggressive males, who normally I'm not used to.
