I have six chickens all have been laying about a month now. My concern- only one is using a nesting box.I lays in a corner of the coop- one goes over the door of the coop and lays in the corner of the barn-one lays on a rail near the gate to the coop(we installed a larger platform for her to keep the eggs from rolling off- and two are just driving me crazy- they are laying from the roost- letting the eggs fall to the ground. The other chickens then run to feast on the broken eggs. I've been checking in on them often and get in to clean up as quick as I can. I have two different types of nesting box - a plastic type from the feed store which they show no interest in and a home made wooden one that one is using. I've tried golf balls. Any advice will be appreciated.
