I have recently moved my flock (couple months ago) out of mobile coops into a permanent coop I built that is 10x10. I had them in a half acre pasture which I built for them which was way too much space for such a small flock. Started with 50 but have culled males for food and had many losses to my dog. Down to 11 adult birds now and since I moved them losses have decreased. they used to see the gate so they would hop on it and then jump down on the wrong side making them lunch for my rottie. realizing that was a major problem I built the perm coop and moved them in there. No gate in the new area so they don't leave that cross fenced area inside of the half acre pasture. Things were great for a few months and I had my first predator strike (outside of my own dog). I wasn't sure what happened and since I found it in the morning I assumed it happened at night so I started locking the coop up which is something I only did in the beginning. I got lazy and never sustained any losses so the birds never got locked up at night. After I saw that bird, I started locking the coop up at night. A couple days later I saw the Hawk feeding on a bird in their pasture. Ran out to scare him off but obviously the bird was gone. I saw he was hanging out in front of the coop door so i thought he was raiding their home so they had no where to hide so I cut a hole in the coop creating a pop hole and started shutting the door. I also added some obstructions in the yard so they could hide and dust bathe under stuff whereas before it was wide open for a dive bombing from a bird. that seemed to help for a week and then today I came home and the hawk was in the coop eating one of my baby birds (6 weeks old). He panicked when he saw me and tried to fly out but he was trapped. My coop is extended from a shed I built years ago and never put soffits on. The hawk went through the soffit from the coop into the shed and out the soffit (or lack there of) on the other side. I obviously need to shore that up with hardware cloth. I am torn because I really loved the management plan I had in place with pasturing the birds. I am realizing I may need to go to the infamous chicken run that many have. I guess I could create multiple runs and rotate them so they could be on fresh grass everday. I have done some googling and reading on here and all I can come up with is I am going to have to create a smaller covered run. I wanted to make the run rather large but that gets expensive really fast. Any ideas on how to sway this bird to leave me alone? Am I just going to have to bite the bullet and build out covered chicken runs for my birds? Just wondering if anyone has any ideas. I know I probably didn't give enough information for my questions to be answered so let me know if you need anymore information. I have another batch of babies that are going in the coop in another week or so and I really don't want to keep losing birds. I have lost about 6 birds in the last 2 weeks. I won't have a flock to speak of at this rate in a very short period so hoping for some good idea. Thanks everyone in advance!
