hi
well the best thing i can think of is to find a cage or something, place the new budgie in it and keep the cage in the avairy, and wait for the new budgie to get used to the other budgies.
Hi,
i have an outside avairy, i just have alot of sand on the ground for the quails that i have, i guess that keeps the ants out, or at least it hides them?!
