Two female birds can certainly be "lovers! I have two sister budgies about a year old, that mate, with one girl on top, and one lays the eggs in her food bowl or onto the cage floor. I take the eggs away as laid. I tried leaving a few eggs in the bowl (they have a three food bowls) but she tossed them out for some reason. She sleeps in the bowl some of the time, too. I can't seem to stop this behavior short of caging them separately and I don't have the cage space. I just give them a good diet supplemented with scrambled eggs for protein and a cuttlebone. I know females can lay without male but two females? These two girls are strange budgies.
