I've just found out one of the reasons my egg count has gone down is that my English setter is going in the coop and eating eggs. She doesn't hurt the hens, she just goes in the hen door and helps herself to the eggs. She has learned that a clacking hen means there is an egg in the nest. I've gotten on to her very time I caught her with an egg, but it hasn't done any good. Any ideas on how to break her of this habit. I don't want to keep the hens in their pen all the time, they like to be in the yard during the day, but I don't want to have to shut the gate when they are out either as they wouldn't be able to go in the coop to lay. I'm open to suggestions.
