I'm pet/ critter sitting for daughter. One chicken hasn't moved off nest for wk or more! ? I don't want anything bad happening on my watch. There's a fresh egg in am, not what she's sitting on. How do I determine she's OK or not? What do I do to help her? There's a possibility, since they do wander country neighborhood, that she's seen a roster! ?!? I'm putting food water near her. Talking Soothingly to her at am feeding time. Do I leave her be, go get a for sure fertile egg for her?! Cannot reach daughter, I live in city lol.
