You were visited by a male kestrel or sparrow hawk..  I doubt he would have tried for a full grown chicken but chicks would have been on the menu..  They primarily eat sparrows (big surprise given their name huh?) mice, other small birds/rodents and insects ie grasshoppers, etc.  
I raised a pair of orphan kestrels from chicks when I was about 12.. They were fun birds.. After releasing them, the male hung around our property for about a month but never bothered the chickens..
