I have a young pair of black masked lovebirds who laid 5 eggs on 22/10/11 which I believe to be infertile. Should I remove the eggs and let them try again or remove the nestbox and give them a rest? I do not think I have two females, as I witnessed one of the birds mounting the hen and assume only the male would do this. I have no DNA proof that they are a 'true pair', but the hen was the only bird incubating the eggs.
