Ive had multiple hawk attacks through my years of having chickens.
They always take my bantams! But they still try to go after are standards!
They are relentless and not scared of humans in the least.
A hawk tryed to go after are chicken (in its pet carrier) right next to us!
I was amazed at the nerve of this bird
They don't have to be circling all the time.
If you have trees near by, they perch on the trees and observe/stalk are chickens till they go in for the kill.
They have become such a nuisance we have to make a roof covered run for them.
Don't even get me started on the raccoon problem we had tonight.
2 huge raccoons the size of dogs were harassing my hen!
We shot them a few times and they just kept coming back...so fed up with things trying to eat my pets!
I would also like to add, crows can sometimes be an issue.
maybe not one by itself but they will often gang up and take smaller birds!
Ive even seen a crow fighting with a vulture over a mouse...they are not as innocent as you think
