what happens with temperature if the cage is stuck outside?

My female has only just started laying eggs yesterday for the first time which is great. but the problem is that the month (here in australia) is the beginning of May, (1 month away from winter) therefore meaning that the mornings are getting colder. with my cage being an outside cage how do I retain warmth so the eggs survive? this is the first 'clutch' I have ever had so I am very new to this whole thing and will be taking it as it comes and hoping for the best.
Another strange thing is I stopped feeding my birds sprouting seed about 2 months ago, due to seasons changing and them not mating. Therefore they have just been eating regular finch seed. So I was wondering now they have decided to mate when its coming into winter which makes it harder for the babies to survive anyway?
First thing I would do is to wait 10 days after the last egg was laid and then, using a penlight flashlight, I would candle the eggs to see if they contain developing embryos. If they are fertile, you will see lots of tiny red blood vessles inside them and you must find a way to heat the nest box if they are to survive. Not being able to see your set up, puts me at a serious disadvantage and I don't know how cold the winters get where you are. Outdoor breeders here in Maryland, will have a shed attached to a flight cage with a window that connects them. The birds can be either in the inside cage or the outside flight. When it gets cold, the breeders here wrap the outside cage with clear plastic sheeting and put an electric heater in the shed or they get all the birds into the cage inside the shed and close off the outside part and heat that. I don't know if this is possible in your situation.
It won't hurt anything to start offering the pair a bit of eggfood and greens again. If the eggs are not fertile that can be stopped and removing the nest box will hopefully get the hen to stop laying. Wish I could be more help, Jeanie
