I have two male diamond doves who get along after a rocky start when they lost their girlfriends. One woos the other. A breeder told me that the best success with a male and female is to get siblings, which are apparently part of a clutch of two which every hatch contains. She says each pair is bonded to the point where they will mate for life after having been attached to each other by hearing each other's heartbeat. (My take on this is that there won't be any variety in the bloodline.) What say you all? The other thing is if I added a single female, would it mean fighting? If I were able two add two ladies, should I find them, would that also cause a problem? Would I need to separate each pair?
