Hello BYC! We are on our first full year of chickens and loving every minute of it. We don't free range, but have a very large 2nd run (about 400sq. ft.) off their main run and would like to plant some bushes, shrubs, etc. this spring that will attract some insects for them and enrich their lives overall. I know we can do butterfly bushes. Any other ideas? We live in Central Illinois (Zone 6) for growing. Thanks.
