Not any really noticeable cockerels with this coloring. She is the most extreme, but 2 years ago, I had a hen who was mottled, but not as pronounced as this girl, and it showed up more as she got older on her 2 year molt. My husband likes me to reduce in winter because I don't have a lot of indoor coop space. He's right, of course, unless I could afford to build more coops, I'm forced to reduce to about 40 birds in winter. She was sold to a lady looking for older hens. This is likely a granddaughter of that hen.
keep her. you might hatch a mottled cockerel next year.
