I live in Pennsylvania, and was thinking about getting two Serama hens. I heard that they do not cope well with cold and that their living area must be 60F or above. Keeping them inside is not a choice, so my only option is for them to live outside or not get them at all. I would be keeping them in a rabbit hutch; I hope to build a run that will go on the ground so they can scratch and do all that fun stuff. I'm really not sure about heating the hutch, since I think it would all just go out through the door. Where I live it tends not to go below 20, but it is possible. I may be able to give them a lamp on colder days, and confine them inside their hutch... I donno. I will go out now to get a picture of the hutch, so you guys have an idea what I am working with.
