their shit is very acidic, and they like to scratch around in the earth.... i hear stories from my family (who were farmers until the communist government said otherwise and took all animals and land) that when they had chicken, there was no grass growing in the lawn....
your place is not always the same as other people's places, so you can't make conclusions arbitrarily.@maxsieg different from my place, we have a special land for chickens, we do not use our home page for chicken land. so that our yard is still beautiful.
