What do they have against chickens?

Day 3 of vacation with the family.  We have discovered something disturbing at our otherwise AWESOME rented house on the beach here in Anna Maria Island, Florida.  Apparenty there are giant chickens roaming the area.  No, that is not the disturbing part... that would be that it seems they bury these giant chickens with their feet sticking out of the ground.  Maybe to scare the others away?  Hmmmm... giant beach chickens.  As you can imagine, the other birds are concerned about this brutality...  I met gulls and sand pipers and pelicans (oh my) convening on the beach to discuss.  

(I also discovered beach doves hiding in the sea grass...doves on the beach???)  I would be worried about this if I weren't reasonably sure that chickens are NOT carnivorous. 

Tune in to our regularly scheduled vacation blogging later...
