Love birds - what gender?

You can't really identify their genders visually. Males and females look identical. If it is a compatible pair, they will produce young. If you have 2 females, they will "play house" and both of them will lay eggs (in which case you will find about 8 or more INFERTILE eggs in the nest box. If they are both males, they will still "play house", but no eggs will be laid.
