I was concerned after purchasing these birds because I live in a very cold winter climate. But they have turned out to be quite tolerant of the cold. They forage outside during high winds, bitter cold, deep snow. Nothing bothers them. At night they roost in between their coop mates for warmth. I don't heat the coop.They did equally as well in the summer heat.
I've also been getting about 10 small white eggs from 2 birds per week. Not bad for the breed.
Due to their small size they certainly can fly! But tend to stay close to the coop with the flock. They get along well with others in the flock and are about middle in the pecking order. They're not friendly with humans, but won't run from you either. Basically indifferent, unless you try to pick one up.....then they're gone in a flash. They can also tolerate confinement, but are much happier free ranging.
Very beautiful breed, distinctive coloring and combs.
