My standard Nns do pretty well (of corse the grandmother is a silkie who loves being broody) I dont recomend crested birds, they can set good but arnt good at taking care of and protecting the chicks.I have always wanted to hatch my chicks out under a broody hen. I had a mixed hen that went broody twice then was taken by a fox. We couldn’t let her hatch out chicks for numerous reasons. I have two buff Orpingtons and none have gone broody. I got a wyandotte chick and she is 8 weeks so she might be able to get it done. I need a LF breed that dose well in cold and heat as for egg color I would prefer a dark speakled or blue/green color for egg color but peach or white would be fine. I have been looking at standard Cochins but what are your thoughts?
