If The Birds In The Tree Flop Together

If the birds in the tree flap together,
Why can't they?
In the matter of two angry baby birds who can't fly yet, They appeared in a dark room,
in the same tree,
 then off the tree,
The eldest pushed the youngest.
Needing help, comfort, and love,
The eldest bird chirped loud and clear,
But could never be loud enough,
So she kept everything in, and grew more angry.
 Being picked on,
Being blamed,
being responsible for the other birds would never be up to her,
She used to always volunteer to watch her little siblings, But even so,
They'd always chirp back,
When they do chirp back
 The eldest would pass into that same dark room in the same standing tree,
and the eldest pushing different young ones.
 When they are angry at her,
 they think of the same but worse,
 they pick on her
 they'd tease her
tell her she's the fattest bird
Yet she still manages to hang on until shes ready to fly. She opens her eyes and stays to herself.
If the birds in the tree can flap together
Why can't they?
