Well shoot. They act fine, they eat like crazy. Their crops are always full. I thought maybe they weren't feathering out because they're still under 90* heat. It's at 88 right now and they're asleep so maybe I'm getting somewhere. I wouldn't dream of having you replace them! It's not your fault at all. And beside I'm already attached to these ones lol Actually the one that died was my favorite, it waddled like a little penguin. One of my Silver Phoenix I got that same night died also. And those 4 had always done well.
