Yea that would make sense why yours dont' scream pcb .. I mean they have so much freedom.

But that shouldn't be too big of an issue with my tiels because they were always caged up anyway .. maybe its the move and not being used to the environment. I hope so .. after all, two tiels screaming in a tiny apartment isn't the ideal working situation, hey!. .. lol

Thanks for the replies guys .. they have quieted down a bit but get all worked up on occasions and sometimes it last for an hour ... *sigh* ..
