Just because birds are your property doesn't mean that gives you the right to do whatever it is that you want with your birds. Pretty sure that abuse and neglect can be fined! Or the animals potentially taken away from you! Killing them is also against the law... One thing to have a vet euthanize a pet for you, it's another for you to intentionally kill a pet.
Unless it's a chicken, a pig, a goat or some other type of animal like that... and you're gonna eat it. Cockatiels don't have very much meat on them anyway, so it seems like it would be more hassle than it's worth.....
Okay, fine. You (
@Cockatielmamaw ) want to breed your birds? (rhetorical question) Are you aware of the proper diet for your birds? Are they eating a healthy diet? (just because you provide a healthy diet, doesn't mean they'll eat it) Is the hen flighted and getting daily exercise? (overweight and under exercised hens may have a higher chance of egg binding) Do you know the signs of peritonitis? Egg binding? What to do if a hen lays a soft shelled egg? Are you experienced in hand feeding chicks? Do you know the temperature the formula needs to be at? Can you hand feed every hour around the clock if the parents neglect, abuse, or over-feed their chicks? Do you have a brooder on hand for raising chicks? Syringes? Electrolyte solution? Are you aware of the dangers of burned crop, slow crop, sour crop, over-extended crop, dehydration? Do you know how to wean chicks?
It's not about the human being, but about the birds! The birds' health! Generally speaking, pets don't make good breeders, and breeders don't make good pets. I have a female cockatiel that masturbates and lays eggs. Does that mean I should get her a mate? NOT AT ALL! The only male that has, thus far, shown any interest in her and tried to woo her over, she completely ignored. I mean, she'd be enjoying herself, he'd get all excited, saunter over with his best songs and wings out trying to impress her, and she'd stop and then walk or fly off. She was raised by humans so she doesn't understand the whole "birds and the bees", and I'm fine with that!
Lady Jane's point is that, if you don't know what you are doing, then you shouldn't be encouraging your birds to reproduce. More harm could come of it with little to no knowledge than trying to discourage the behavior. So okay, what if you don't know how to hand raise the chicks and you don't have the equipment to do so anyway? Birds have been raising their own offspring for centuries out in the wild with no help from humans! And that's fine! But what if you end up with wild chicks that want nothing to do with humans? People aren't going to want a pet that takes time to work with in order to get them socialized with humans. They want the instant gratification of having a pet that already enjoys human companionship. Or what if you end up with chicks that you have no homes for? And you can't find homes for them? Can you financially care for more birds? Do you have the space for more cages?
Simply put, breeding birds is nothing like breeding cats and dogs. You can get human friendly kittens and puppies simply by playing with them as they grow up and their mothers raise them! Try that with birds, and good luck! You have a higher chance of the chicks thinking you are a predator rather than a companion. Not to say it's impossible, just birds are a completely different creature to mammals, and require a lot more care when it comes to raising them.
Being a breeder, even if it's just as a hobby breeder, should be done with responsibility, care, forethought and with as much knowledge and experience as one can get. Having a mentor (i.e. another breeder) can greatly help in case problems arise! And an avian vet, too!
@nabeela A seed only diet is not very healthy for cockatiels. If you have access to pellets, they would be a great addition! Vegetables and some grains and possibly legumes are also essential to the diet. Adding vitamins may help, but it's not the same as her getting fresh foods. (are they eating vegetables every day? or still having problems getting them to eat healthier?)
If you have the same cage you did 8-9 months ago, it is too small for them to be breeding in. You will need an additional cage anyway for any offspring, if you do have a proper setup.
Raising a pigeon and raising a cockatiel are two completely different ballparks! I would say that it's probably easier to raise a pigeon than it is a cockatiel!
As far as egg laying goes... generally, the female puts on weight (gram scale...) when she's "with egg", and her rump will become enlarged. Here are some images of what "egg butt" or "egg bum" look like.

I'm sorry that you live where you do and you may not have access to as many luxuries as many other members of this forum do, so you work with what you've got. That you have a vet (doctor) that sees birds is great in itself!
I'm in agreement with Lady Jane, in that if you don't know what you're doing, it's probably not a good idea to encourage them to breed. That said, it's still a good idea to know what to look for, if things ever get any further than mating and doing as much research as you can now. You can try increasing or decreasing the amount of daylight they get to try and discourage hormones although the best way to prevent them from having a family is by not allowing them to be together. Hopefully, you can continue to keep them together and Spiky will never lay eggs! If she does, we can try preventative measures from there! If you can buy dummy eggs, that'd be great! If not, well, we'll work with what you do have!
