Your words... "worry", "load". I could copy/paste the webster's definition of these words for you.If you have all this stuff going on, why would you want to foster parrots, and throw more of a load on yourself? I would just get all your animals squared away before you worry about helping other ones.
Load:
the quantity borne or sustained by something; burden: a tree weighed down by its load of fruit.
Worry:
to torment oneself with or suffer from disturbing thoughts; fret.
Nope, I'm not fretting. Do you think you might be?
