I agree with camire77's post, it's very much identical to the experience my hens had; I've never had Polish but had mixed breed chickens with the same hairdo on them, and it did impact their quality of life very strongly... Everything from social standing and perception, to ability to forage or compete for the best treats like grasshoppers, etc... They were mentally 'quiet', no personalities, until trimmed, and man, what a change that made!
First they would just stand and stare in wonder at the world around them, then they became bold, active and curious animals, developing lively personalities, taking higher social standing, becoming interested in the world around them which they could see almost nothing of before. Huge differences.
Unfortunately Polish hens, or those with similar hairdos, are effectively living in 'blinkers' and it really does have a serious impact on them, even if they're caged and have everything 'on tap'. They are effectively only listening to the world, if the hairdo is thick and low enough, unable to see it. Their mentality and learning is limited by that. My Polish-hairdo-type hens used to be as silent as ghosts, to avoid attracting attention they couldn't see coming, walking around with their heads very low to try to see the ground, staying near walls so they could find their way around as they had no long range vision due to the eye muscles responsible for focus being weak due to lack of use, due to the feathers constantly preventing them from focusing on distant objects... Pretty tragic lives.
Best wishes, hope it goes great for them.
Fancypants1, good luck changing your bully, but if it fails I hope your trimmed Polish can change the status quo and put the bully in its place. I prefer to remove bullies permanently but each to their own.
Best wishes.
