I have a flock of 12 chickens ( 11 hens and 1 roo) mixed ages and breeds. They are free range durning the day. There is a little door cut out in the big door for them to go in and out as they please. A few weeks ago I went out to garther eggs and someone had pecked a hole in an egg. The problem slowly got worse until I found 3 eggs that had been broken open and partially eaten. By this time I am pretty mad and am ready to take some action. I go into the coop the next day and what do I see... A darn magpie eatting chicken food! I flew out and it dawned on me it was magpies getting the egg! Now my question is how do I keep them out? I can't keep my girls lock up. Any suggestions?
