One of my black giants went broody over the weekend, and I was planning on putting a few eggs under her on Saturday. But today I came home to find one of my buff orpingtons sitting in the same nest! It's a tight squeeze but they both fit, facing in opposite directions. I don't know if the orpington is going broody too, but if she is, I'm wondering if it's wise for 2 broodies to share a nest and eggs? My hens all get along really well, but I don't want to set the stage for potential fighting over chicks or other unforeseen conflict. Any advice?
