if i go into my coop and it is somewhat dark the roos attack.. during the day light they are fine.. but sure am glad i had on jeans and boots they were vicious. the girls are fine no matter what. you can hold and pet them.. you would think they would recognize my voice when i talk to the roos but no way.. they want blood.. i literally threw two out the door so i could pet and hold my hens. it was dusk out and a little darker in the coop. so question is can they see in the dark?
