Can Chickens get depressed?

Question

Recently one of my Roosters ( 1 of 3) died of unknown causes. He was very young only 2 years old. We have 17 hens and during the past few days they have been laying less and the other roosters have stoped crowing. I just wondered if Chickens can mourn. Oh and there breeds are all bantams( a mix of white porcleins, Conchins, sillkies, and mixs) the Rooster was a porclein
