What makes you feel birds aren't good for an apartment? I got my tiel Dawn while I was still in an apartment 5 years ago and it was no different there than in the house now. The only thing I can think of is a possible noise issue but tiels are one of the quietest birds I've been around and I've seen/heard of many people keeping birds in apartments.

I don't know what your situation is exactly but I wish you and Lucy the best.
