I have 2 female and 1 male cockatiel. They are in separate cages although are next to eachother. the male is in the middle. he is in love with "Gizmo" but not "Hen". Gizmo and Buddy (the male) do alot of screaming!! Hen just typically chirps and occassionally screams along. This is driving the household nuts! I hate to cover them all day and all night. Any suggestions????
