Irony or protesting?

Neither; they're trying to avenge their brothers death. Look at those faces- those are the faces of killers.

Suicide maybe?

I was once at a restaurant in Thailand and at this place they had free-roaming chickens who just went around the place, a bit of atmosphere I guess. Anyway, so I was having some chicken for dinner, and me being the clumsy eejit I am I dropped a wee bit to the ground accidentally, before I even get a chance to do anything a live chicken comes along and eats his fallen comrade's meat off the ground

Why did the chicken cross the road?

Look at the little baby chickens next to the people! Aw, they're so cute. :)

Am I the only one that thought of ashton irwin?
