If they are like chickens, and I say they are....they can't see crap at nighttime! If I leave the coop door closed and the chickens can't get in to roost at night, it is an act of congress to get them in. They can't see the opening of the door right next to it. I actually have to push them through the door opening. I don't wash my clothes in UV wash. I have killed all my birds in regular camo or once in an orange t-shirt, as I was shedding some clothes due to it getting hot. He rolled right up in there on me. Grabbed my gun off the tree and "HE GONE!" So, OG nation, I will be selling orange tee's soon if-in your all interested.
