Right! Bird expert on the scene!
Don't put the male she attacked back in with her. If she doesn't like him, there is no way they will mate, budgies are very aggressive and one of them may get killed.
Birds have to mate before making each egg for them to be fertile, so will need to do it several times to make a fertile clutch. They lay one egg every 2 days, and need to mate each time before the egg is laid. Both birds then raise them - usually the female will sit on them and the male will eat and go back to feed the female. A male and female need to be kept together right through the whole process until the babies are fledged and have left the nest.
Did you actually see the birds mate? A female will lay eggs during breeding season regardless of whether she has mated, they will of course be infertile.
Birds mating is a tricky business. They don't have 'equipment' like mammals - they rub their cloaci together, and it is a bit hit and miss. A young pair of birds need to practice before they get it right. They also need steady perches to stand on while they are mating.
A pair of budgies kept by themselves will rarely mate and produce fertile eggs. Normally they need to be within sight of at least two or three other breeding pairs (although not in the same cage, budgies are aggressive).
Is the hen getting plenty of calcium? She may become eggbound if she keeps laying and isn't getting calcium supplements. Make sure she has a cuttlefish bone or calcium block available.
Don't incubate the eggs unless you are experienced at hand-feeding and have the time to do so. Newly hatched babies need to be fed every two hours throughout the day and night for the first week - which means no work and no sleep. It is easy to kill baby birds when feeding them if you don't know what you are doing.
Budgies are excellent parents. Your hen is not sitting on the eggs because she knows they are dead - so an incubator would be pointless. If she had laid some fertile ones, she would be an excellent mum. She is the best one to sit on them and feed the chicks when they are born.
Do they have a nestbox?
Do they have high-protein food for breeding budgies?
How old are they? You should not be attempting to breed budgies under the age of 2 years, but after about 5 years of age they will be too old to breed.
Are you sure you want them to breed? There are so many unwanted birds around already, and many are neglected and mistreated - are you sure you want to add to the problem? How will you find homes for the babies?
Go to this forum, it is excellent - I am a regular there, and there are lots of experienced owners and breeders and even a student avian vet who post there - you will get lots of help from them if you introduce yourself and ask them!
