Ok... am tired of this little hen. She has been sitting in a box for over TWO months now . Probably 10 weeks now. I never see her out eating or drinking unless I force her out of the box. I've tried putting her in the run in a section she cannot get back to the boxes, but she paces and paces and paces for days .... and the minute I let her out of the seperated area she goes straaaaaaight back to her nesting box. How LONG do these silkies stay broody? Is there any hope!?
