Oh yes loads of bushes around the tree's and even some in their run, and a couple of tree's in there as well.
One chicken was attacked in the run - I stopped them or rather scared them off. The other two which were killed were killed on the lawn area, we have about an acre and a half of this where the chickens roam about with trees & bushes, etc. We are putting salmon netting over the runs now, but really can't protect them when they are roaming about.
I did read yesterday that Raven's were not common and were protected - so no more trying to scare them with my pellet gun I suppose. I must admit I didn't realize they were protected until then, but you don't always think about this when they are pecking your poor little white hen alive in front of you. Even the dogs were upset and laid there sulking afterwards for about an hour, just pleased grand-daughter wasn't here.
Fingers very crossed here and I've roped my mum in to go shopping today so that I can hang about and watch out for them.
