today i was inside and i heard one of my hens making a lot of noise and i thought nothing of it because she always make a big deal about when she lays an egg or if she found a bug and wont share, but this time she kept going on and on so i went out side and just as i went outside a hawk flew away so i quickly ran over to the hens and started counting my chickens and ducks, luckily they were all there, i am starting this thread because i am wondering what should i do to keep hawks out of my yard, i have never thought about it before because we live in town, but seeing that hawk scared me, i was expecting to see blood and feathers.
