Coloradogal, I can't begin to tell you how tempting it is to snap up some Marans chicks, but I have just been NPIP certified and if I get new flock members from non-NPIP flocks I lose my certification

I know how silly it seems for 7 backyard hens, and I don't even know if I can say exactly why I want to maintain it, except the hope in the back of my mind that some day I will have eggs and chicks to sell.
Since you have both Marans and (I think you said) Aracaunas, maybe you can tell me how you feel each has fared here? Not only do chickens in CO have to be cold tolerant, they also have to be heat tolerant, predator savvy, and human tolerant

Those who like to forage may have little to forage on during the hottest months of summer, do yours seem to manage well during July and August and into September?
