Birdie's tounge is working fine.I'm not sure if it's super strong yet because he's still stained.But he's getting stronger everyday.Especially when Marshall and Tucker visit him a few times a day.Him and Marshall like each other.Tucker is liking him...a little.Birdie seems still fragile but really improving.I hold him in my zipper sweatshirt for lengths of time during the day like a Kangaroo mom.He likes that.
