Our lawn is in pretty bad shape, and we were going to re-seed this year by raking good and putting down appropriate grass seed. But duh, I won't be able to free range my hens during this time, right? They'll just eat it all up. I don't have a big run for them (7 hens, 3 roos in a 4 x 8 coop over a 4 x 8 run) since they run around the yard and into the woods all day long. Do I have any options other than building a bigger run?
