Ok my guys free range all day. They come and go to the coop when every they feel like it to lay. They door is about 12" wide and 15" tall. I was getting 6-7 eggs a day then 2. While washing dishes I happend to look up and see my Black Lab comming out the coop door with eggs in here mouth. I was so mad. I stopped doing dishes and went out and spanked her butt. She left them alone for a day then right back at it. I can not chain her. She will dig it up or pull it out. Kennel is out of the question she dig out. Even when we drove poles in the ground. How can I break her of this nasty habbit. I really do not want to cage my chickens. I do not think it is fair to them. Any ideas? Shock collar is next.
