Please tell me if I'm right, wrong, or a little of both. Every day I pick some fresh grass and put in the coop with my 4 - 7 week old Barred Rocks. I was thinking, by putting fresh grass in every day, it will help them from eating all of the vegetation in the run or at least slow it down. They've been on the same 4x12 footprint for 3 weeks now and while they have eaten a good bit, no part of the run is down to the dirt yet. Am I right or misguided? I'm trying to keep from having to move the coop too often.
