IMO, Polish chickens should only be kept with other Polish birds because the crest or head dress on the top of a Polish chickens' noggin results in the poor Polish chicken forever blundering into the personal space of higher ranking birds and paying the price for this preceived violation of the pecking order. Getting rid of your cockerels is not a solution, your other hens will more than make up for any bullying (if any) that your young roosters may inflict.
