I have a 13 month old red rock hen who has decided shes not leaving the nest. as a result, the other girls will not come in the coop to lay. they have a huge area to roam and therefore we are literally having a daily egg hunt! We do not have a rooster and i take the egg she lays away immediately. i shoo her out to poop and take the food and water away during the day. I have tried laying a piece of wood in the nesting box and she just sits on the wood. Any suggestions?
