Hmm.. they do well in a mixed flock. Not sure about the temps. I would think if you have a well built coop that blocks from the weather and lots of other birds to snuggle with they should be fine. They are hardier than they look.I do not have any necked necks but do plan on getting them in the future... Would you recommend this breed to live with other regular chicken breeds? It also can get -15 over here is that a problem with this breed?
