My wife keeps trying to convince me to get rid of the normals, my rack has room for 7 more.... so I dont have to worry too much about the new rack issue.... YET.

I agree with Ed though, if you sell some of the hatchlings off and get her something she wants she may be more willing to accept a new rack. I know my wife wouldn't mind something nice and new that she wanted, and then she wouldn't mind letting me have what I want.
