I can believe marigolds repel bugs they stink..lol...very pretty though. I do have hollyhock planted around my shed and they are biannual but should reseed themselves. There are Zebrina malva and blanket flowers nearby too that will help attract insects. After reading the link... herbs for healthy chickens that Janet provided , I am convinced those nasturtium are gonna go around the base of my run and it won't harm my birds if they eat emmarigolds repel insects. chickens do love to eat the flower though. I am wondering about sun flowers ? there are so many different ones. different heights. hollyhocks are bug magnets but a lot of them are biannual .

Thank you all for the suggestions. I have to get ready for work 2 more 12hr nights before switching back to days. Have a great night!
