wow! going to have research prairie falcons, i have read some cases where hawks will hunt in packs- one lucky boy you have there!I heard something down by my pens once. I heard a 2nd noise so i stood up and started to walk towards my pens. A barred cochin rooster i had living with the goats was sprinting up my dirt road towards the goat house. He had a prairie falcon flying about 6ft off the ground hot on his trail. I lost a big black hen to the prairie falcon and several others of diffrent breeds. He would have caught up to him if i wasnt there but that big cochin ran pretty darn fast.
