Im in London near Greenford and it gets fairly dark around 4pm now and yesterday I put them in near 4 45 and I found out one of my chicks is missing. I have a suspicion that is bird, particularly seagulls, swooped down and took it. All my family are in despair and utter regret. its unlikely for any other creature but I am worrying about the rest of the flock so any advice on how to avoid birds coming down? is there a some sort of net I can put over my garden which is fairly cheap? thanks
