I have a broody buff orpington right now; she's been sitting in the nest box since Friday. I'm thinking of giving her some fertile eggs to hatch, but am new to this and have some questions. Can a standard-sized hen hatch banty eggs? Would she be too heavy for them? Can she hatch duck eggs? Will she know how to care for the chicks (or ducklings), or do I need to take them away? If she hatches some babies, when can they rejoin the flock? (There are only two other hens. I haven't noticed a "pecking order", but I'm sure there must be one.) Thank you in advance for your patience!
