I have only two brooders i keep my chicks, ginea fowl, and ducklimgs together in the larger one and keep my two geese in the other. I had two ducklings that were too big for the chicks anymore so i decided to put them with the geese. The next day i found out that the ducklings were dead. The seem to have been killed by the geese. They were of similier size the geese were just a little bigger so i dont think they were stepped on and crowded out. Do geese normally kill other birds?
