I would not use straw bedding that is freshly from the coop in a bed that i plan to plant this year. It is best to let the chicken poop compost before planting near it. I just made new beds this year and used fresh new straw. Now i would rec commend that you try to find straw that is not seeded...
I roto-till straw into the soil wherever i want to plant something. It helps keep it from becoming so compacted again... It usually lasts about 2 to 3 years before it needs worked again.
