I'm not sure now what my original question was. My head is spinning with all the places Google has taken me today in researching your replies. I am working on a list od questions for you guys, if you all don't mind. I just want what will give TD the closest thing to a natural life that I can. I want him to be happy being a bird....was your question ever answered?
Not sure of my original ?, but I do remember that I was very happy with the answer from @JLcribber !
