Thanks everyone

for the advice. I will try to greet and also feed the Amazons first and see if that helps. I've kind of been doing that but will pay more attention to it and be sure to do it consistently and hopefully it will help.
This morning I let the Amazons out of their cage for about 30 mins, the house was calm and I was just watching tv so I thought it would be Ok. They sat on top, didn't try to attack me at all, and then when I asked them to "get back inside" they went right in without incident. Yay! The Grey was inside his cage and all 3 birds were quiet the whole time.
The way my house is set up I don't have many options as far as separating them further, unless I put one cage in a bedroom and then he'd be away from people most of the time.

I'm thinking I'll just have to wing it (haha) with the way they are now, somewhat out of sight - Izzy is under the stairs (it's open) and the Amazons are next to the stairs and can only see eachother from certain positions in the cage. I'll need to be patient and stay as calm as I can when there is screaming, etc. Hopefully there will be no more bites.
I will look for a clicker the next time I'm at the pet or bird store, and try clicker training inside the cage. Thanks for that idea. I'll look at that video that one of you suggested too.
Have a great weekend everyone.
