Someone please tell me, if a broody leaves a nest of eggs and goes sits somewhere else, how long do the embryos inside stay alive? I have some of the weirdest cochin broodies. Good broodies, but they keep picking different places to nest. One will pick a place where the eggs I mark will get crushed because the broody picked a busy nestbox, one will sit in a good spot for a week but decide after eating to sit in a different nestbox, and sometimes they just stop entirely. I'm frustrated with this and the parents won't let me get an incubator. I have the money too. Ugh My only good broody is a andalusian cross we call Mama. She does everything very well, and when I move her when it gets to hatching week (or I worry about eggs being crushed) she stays in the doggie house. I'd love more chicks but I can't seem to a perfect broody.. Mama is still taking care of 8 week old chicks.
