Beautiful birds! Someone's put in some serious time and attention on the breed. Some of the best leg scaling I've seen on this site so far, too. I was beginning to think only Aussie chooks had normal leg scaling almost as a rule...
If I'm not very mistaken, there's nettle growing around their run. Is that deliberate as a dietary addition or a hedge?
Also, why are the images labelled as 'aracuana' when I look at them in a new window?
I notice they also have what appears to be a plant from the milkweed family, possibly dandelion, I'm not sure since the bird's in the way... Is that a deliberate run addition? I'm not sure about some of the other plants but they ring a bell, though not for poultry use offhand.
