We are almost finished with our coop and run. Still have some wire to put in the ground around the run and coop. Seems to have a few areas on coop that need addressed in regards to possible predators, but will be introducing our chickens to the coop/run soon. We are concerned that we have found mushrooms growing in the run area. Will this cause the chickens to become sick or will they avoid them? Concerned about this situation. Thank you for your help.
