I have a very dependable broody/mama Java hen that has accepted and raised adpoted babies several times for me. I also have a rather unhealthy duckling obsession and really want to get some, lol. I've heard of people using their broody to raise ducks, but does it only work with eggs? She has accepted adopted babies of the chicken variety, if that makes a difference. If this would work, anything I need to know or keep in mind? Thanks!
