I used to let my hens free tange but then we got a batch of crosses that were to dumb to back in at night so we started locking them in run. I have a few girls who know how to get out and I dont mind as long as the meat birds stayed in. Now that they are all processed we alstarted letting them free range again. Now i have gone from 7-10 eggs a day to 4-6 eggs. I locked them in the run today and only got 4. The usual ones escaped but they always used lay in the coop even when they escaped. Any Suggestions? They are only 6-7 months old. I searched for another nest but couldnt find anything. Now my dog has been chasing them and actually killed one a few days ago. Since then he has been leashed while outside. Maybe stress? Any suggestions are appreciated
