I'm considering spreading mulch around where the chickens, ducks, and guineas hang out. Some would be inside the yet-to-be-finished chicken run between two coops, but also around a big area that includes a building and a big covered cement slab, in addition to the coops. It would look good and really help with mud problems, but I'm wondering if it would be harmful for chickens? I know they will peck at it, and I'm picturing pieces of wood going into their crops. The mulch is mostly shredded live oak trees and some cedar trees. They have free range on 8 acres, but tend to stay in the front four acres, in their "area" close to our house. They can get away from the mulch and have plenty of places to get bugs and scratch and dirth bathe, etc. so that is good, but I just wonder if the mulch could harm them. Any ideas and suggestions will be much appreciated. I'm up against a blank wall in my mind here, and since spreading the mulch will involve getting a big piece of machinery out here to move it around, and lots of work for the driver, there will be no going back once it is done. Thank you!
