i THINK this particular bird is a cockeral. 'he' was on one side of the fence, starring down a silkie on the other side of the fence. all of the sudden, the feathers around 'his' neck stood up in a circle! just like the dilophosaurs ( the one who gets fan like scales around his neck and then sprays the bad guy) in jurassic park!!! kinda freaked me out. none of my other chickens have done ANYTHING like this! i "believe" this chicken/ cockeral is a Delaware mixed with something else. anyone ever have an experience like this? thanks!
