Hi Barb, I'm glad your bird is so tame, she sounds really sweet. When you give her a spray bath does she hang upside down? My bird , Zoolie loves his bath and does that..hahaha he looks like a fluffy bat! He stretches his wings out too hahaha. You were asking if I thought birds are happier with at least two, yes, in my opinion, I think they are. Many bird owners might disagree with me. And I have to say , I've seen birds that seem very happy with just their owner, so maybe I'm not right. It's just that when I see my boys interact with each other, like grooming each other and eating together, they just seem "right" and so happy with each other. And you asked what my Linnie's like to eat. My breeder sent them home to me with them eating pellets and a good seed mix from Higgins. They were also started , by her, on romaine, and apples, ect. They really love apples. I also give them carrot sticks and grapes, cukes, watermelon, just about any fruits and veg. that we have around for us, but always romaine. I hope Hollie will "try" some of these, I'm sure it would be really good for her. I really don't think my boys eat their pellets much at all, seems like I throw those out when I clean the bowl each am. But I keep putting pellets in for them anyway. Oh, and as far as their age goes, they had their first birthday this past October.
