We have 17 chickens (3 Bared Rocks, the rest mix of Easter Eggers and Golden Sex Links). We have a coop with an outside run. We also let them free range. We have been having low egg production. Our 10 year old son went under the coop tonight and found over 60 eggs under the coop. Ideas? Do we just not let them free range anymore? I am afraid if I board up the bottom of the coop they will hide them another place. Thanks!
