Unfortunately our chickens can't really be allowed to free range. They are 21 weeks...about half of our 8 hens are laying. They are also looking really bored. They have a 12x12 coop and a 12x8 run. I've noticed that they are starting to dig in all the corners and by the door of the run. I know they would like to be let out to roam the yard but I don't see a way that could happen due to our other animals and other issues. What I was wondering was if anyone had any suggestions for keeping the ladies entertained? I'm pretty creative but new to chickens so I could use some help.
