One of my hens several weeks ago got out and wouldnt come back in so I left her. As it decided suddnely to become winter, the other night I figured time to go find her and bring her back in. Ha! Found her in a hay bale brooding. On about 16 eggs now shes a cukoo marans and so are the roosters. Eggs started hatching out Saturday night. ????Yellow??? I dont know what to think.
