I have a broody Silky who had 6 eggs a few days ago. She had been on them for maybe a week. I'm not sure when she started. Today there are 9 eggs under her. I marked all 9 so that I can be sure to remove any new ones the other hens might lay, but will it be a problem that the eggs were laid up to 5 or 6 days apart? If any babies actually hatch, do I remove the unhatched eggs so momma can tend to the chicks? I thought of trying to candle them and see if I could tell which were further along in development, but I haven't candled before and I'm pretty sure I would mess that up.
