Ok, so when do you know when a hen is ready to sit on the eggs, to hatch them. Theyre about a year or so old. They lay theyre eggs and I pick them up at the end of the day but never saw one interested in sitting on the nest. Is theyre some tell, tell sign that lets you know? Long ago when I helped my uncle on his farm, we mostly incubated eggs when we wanted more chicks, which was pretty interesting in its self. Thinking about buying an incubator but would be nice to have them hatch naturally.
