So I just got a new coop since we are adding to our flock. We have a problem with predators that dig, such as raccoons and coyotes and opossums. So I have to have the bottom of the run have welded wire grate on the bottom. I was wondering if anyone has ever tried growing grass through the welded wire, so chickens can have grass in their run. I hate when they are stuck in a wet muddy run when it rains. And the grass would make for easy cleaning and plenty of food for them to eat aside from feed. If I try it I'll let everyone know what happened. But if someone already has, I would appreciate some pointers.
