Petting Pen...Times Four

I watched a lot of Sesame Street when my 3 children were growing up, and this collage reminded me of one of the sketches that the troupe routinely performed. The song went  something like this:

"One of these things is not like the other,
one of these things just isn't the same.
Can you guess which thing is not like the others...
by the time I finish this song?"


Sooo...which animal DOES NOT fit into the petting pen title?

"One of these things is not like the other,
one of these things just wouldn't stay calm.
One of these would peck kid's hands off...
and you guessed right...it's TURKEY TOM!


P.S. Oops. Forgot it was my three grand blip. That be a lot of pictures.
