Hi,
You can’t move birds around with other mates for breeding. This isn’t how it works with birds. The male and female have to bond and once they do have eggs, both the male and female care for the eggs and the chicks. You need to leave the female with one male, period. Laying eggs is very hard on the female and if she lays too many eggs, it will kill her. Your birds should be at least 2 years old. If they aren’t that old, none of them need to be together. If they were laying 2 eggs a day, then both birds are females. Two females or two males will mate just like a male and female. Basically you have these birds very confused. Settle on a pair, and do not separate them once they have bonded. They mate for life, so this means never separate them. It is cruel to separate a bonded pair. As for the third bird, wait and see if it lays an egg and if so, you can see about getting that bird a mate. Never have more than 2 birds in a cage for breeding. Also, an odd number of birds in the same cage is not a good idea, especially lovebirds. The pair will most likely kill the extra bird if you try to put them all together again. Most importantly, again, please stop moving the birds from one mate to another – this is not natural, and at some point a bird is going to end up dead either from laying too many eggs or from fighting because you keep switching them around.
Thank you for asking Lafeber,
