I acquired some Barred Rock mixes as rescues and was having a good look at them in the sun today. They're not solid black and white; three of the five have distinct gold feathers on their breasts and bellies, and one of those has light brown barred feathers on her legs. The other two are so badly molted I can't tell if they're going to be the same or not. Is this a normal 'off' color for Barred Rocks? I know these can't be completely pure Rocks...they've got grey, slate, and white legs. Not one has yellow.
