When I was a kid my mom hatched duck eggs in a plastic shoebox with a goose neck lamp over them, spritzed them a couple times a day and turned them a couple times a day. Can I do the same with my silkie eggs or do I need an incubator? I have a broody Buff Orphington who is sitting on 4 eggs and I don't think I can fit anymore under her. My other hens don't want to nest. What can I do? Thanks!
