I have 2 greys and an Amazon. My schedule went from 4 people minimum in my house , and me being home much of every day with my birds out of their cages, to just me and my 17 year old who is rarely home, to me working 9-10 hour days 5 days a week and them only out when I get home in the evenings during the week. . I have extra large cages for them, leave the tv on when I am gone, but I feel very guilty. They seem to have adjusted ok, I know they would prefer more time outside as before, but when they are out, they are the center of attention as I go about my evening.. I include them in everything I do. In the mornings as I get them breakfast, I am constantly talking to them so they get some attention.
I find them to adapt very well to changes as long as you their flock member is consistent with the attention they get quality wise.
