Cindy, I'm so sorry for your loss. Those little birds can grab your heart faster than anything. When my boys were quite young I took in orphans for a wildlife organization in the Phoenix area. I took all the training offered and learned many things to do. But sometimes, they just break your heart. Such delicate creatures and so beautiful.
I believe you should call a lawyer before calling the flooring company. You deserve compensation. What if you have to rehouse all of your birds? What if the flooring has to be removed and replaced to make your home acceptable? What if you and your human family has been exposed to something harmful? This isn't 'just' a lost pet. You have dangerous, deadly fumes in your home and t hat's horrible to consider. Call a personal injury lawyer right now.
