I have a few hens who's crest look like that (when not in molt). Unfortunately I didn't plan on posting pictures of my polish, just on asking and learning. So I didn't get any pictures of them before they started molting, and now they don't look so hot
. Most of mine seem to be pretty even on the brain side when it comes to chickens, but I have had a few that umm.. well... would fly into a wall a few times before they figured out they couldn't go that way. Since I don't show I have cut the crest on some hens so that they could see, as some were starving to death because they couldn't see through the feathers. I have silver laced polish and working on a blue laced polish, which is coming along nicely.
Hoping some experts on polish comes along and gives some great information.
