Please don't put them outside to live in this weather. They need to be introduced to outdoor living during the summer months so they can acclimatise. Mine live in a big aviary but also have an indoor flight for the night in a big shed and they can go in and out as they please. They have a special heater that we put on if the temperature drops below zero but again, they are well acclimatised and have been outdoor birds for many years. Don't think abouit putting them out until the summer. Mine have an aviary 10ft x 8ft x 8ft and an indoor flight of 8ft by 4ft and about 4f high with high perches in. Mine live with budgies too. If you put them out now you will probably have dead birds the next day. They really need somewhere to go to during the night like inside a shed where they are out of the cold and wet. A wet bird will quickly come down with illness. How big is the aviary you have made for them?
