White crested Polish have a white crest that is wacky in the roosters making them look like arock star hair style.  Pullets and hens have a rounded fluffy crest. They are tame, but their behavior can be a bit wacky since their crest limits their vision. When in a flock with more aggressive breeds, Polish chickens will tend to be on the low end of the pecking order. They will lay around 150 eggs per year.
