Lucy and Alex are like that all the time.

aside from roosting time, they can rarely stand to be less than 6 inches from each other, and so help us all when they want to eat the same thing. Alex also had the tendency to grab Lucy's tail feathers whenever he got the chance, though he kinda grew out of that (to be fair, Lucy also sticks her tail in the air like Beaker does, whereas Alex just kinda drags his).
