Chickens flapping

OK so.  Who knows what happens when you yank a chickens tail when it is on the roosting bar???
This

Flap!

Want to know what happens when you yank the tail a lot?

Flap flap flap flap flap flap flap flap flap!!

My sister took two red armies (red pullets)  And started pulling.  Here is what happened.

Flap flap flap flap flap flap flap flap flap!!

Except it was chicken 1, chicken 2, chicken 1, chicken 2.
It is funny.  My sister discovered it when we were playing in the coop when the chickens were in bed.
While we were out there I put my hand in front of a mystery chicken and it bit/pecked me.  I think it was Willie.  He is one of my roosters.  I still don't know who it was.  My dad thought the chickens flapping when you yank their tail was funny.  It is funny.  We also held some chickens.  It was fun.  When you hold a chicken and move it around a little its head stays in the same spot.  When you take Spark and flip her bottom up her tail feathers expand.  Spark is my sister's chicken.

Lots of flapping.
