Hi Jamie,
My Grey's have the same cage day and night and live in an area of the house that they can see (and be part of) the daily activity, but we can also shut off their lights in the evening and they sleep while we do other things. We generally keep our house at 65 degrees in the winter. I've worried in the past that it may be too cold for our birds but I've spoken with some avian professionals in the Mpls area and they indicated that many birds often do better in homes they are kept in the upper 60's. I've had Grey's for 5+ years and never had any trouble with sickness, any indication the house was too cold, etc. I would however, welcome feedback from others on their opinions about room temperatures. My sister also keeps her home cooler, but each of her parrots has a heated perch on their cage. Once your Grey outgrows his plastic bin, you may want to invest in a sleeping cage with a heated perch, it may be a bit more economical than turning up the heat in your room. Just some thoughts. We're looking forward to hearing all about Romeo when you get him home!! Don't forget to include some pictures.
