I only have a few chickens. Currently only 5 and at maximum only 8.I'm so amazed at the depth and richness of your pasturage. How much land do you have available for them to forage? Do you have to redistribute it occasionally to let it recover while they work over a different site? (fencing, etc.)
They have a very big area enclosed by an electric fence. Nothing like the acre that I think @Shadrach tells us they need, but a lot by backyard standards.
They don’t ever manage to destroy it except for a couple of favorite dust bathing places.
I basically let it run wild but have a shrub planting program to create better aerial protection. I can imagine going fully free range when I have more shrub cover, but I have a heavy predator load so have been nervous about that.
