Have bielfelder hen that has been sitting on eggs. Started hatching last night. Saw three this morning. Found one in hutch, out of nest, wet and extremely weak. Have another hen now trying to sit on nest with broody hen. She still has several eggs under her. Should I do something to protect the chicks or will she take care of everything. I have placed food and water near her. The other hens and rooster have been curious and checked on her through the day.
