Hi, I have a pairs of 12 lovebirds in one big cage and holes for their nests. I have seen 2 male birds trying to mate but the female do not want to mate even though they are sharing the same nest and spend time together. I thought the nest is not preffered by the female to lay eggs so I made the nest more better by adding newspaper slices and wood chips like before but they throw them out. I really want them to lay eggs. What is the reason for them not mating and how can I make them to do so?
