Help! I am trying to help my son raise 4 baby chickens (currently 6 wks of age). We got them 5 wks ago, and currently are living in a large dog crate in my son's room. Although most days are nice here in southern NH, most nights have been very very cold, and I am not sure at what point the chickens can live outside (soon I hope). They look to have their head feathers, but I am guessing, for I really don't know what I am looking for. So I guess, when can I put them outside (we have a nice coop with an enclosure for them to roam in)? Should I bring them in at night? Do I need some kind of heat in the coop, and if so, what does that mean? Do I need to get an electrician out? Any and all help is appreciated.
