Many years ago I had a 'banty' pair of these chickens. I thought they were called 'Old English game hens' but the photos I see on Goggle are definitely not the same birds.
My birds had ENORMOUS breasts/thighs and drumsticks. Their legs were really thick for the size of the bird.
The most pronounced thing about them was their legs were so far apart. Forgive my 'art work' but it does show how far apart the legs were. Also the birds were very squat/short. If memory serves they were supposed to have been breed from 'fighting cocks'. But that may not be so. They were dark brown and 'rusty orange colored.
Does anyone recognize this bird. It's driving me nuts!
