WJ read the other threads and also on the Lovebird forum. There are alot. Yes you have a hormonal imbalance. The basics are essentially:

First decrease the protein. Give fresh foods as described on here. Dark leafy greens, grains, fruits, veggies, breads etc.

Then MOST important lengthen the nights to 12 hours. Birds wont normally lay or even breed in short days. Even following the natural daylight schedule is usually enough. Remove anything resembling a nest like logs, boxes, even allowing her to nestle in your shirt or behind a cushion is bad. Also move the cage around to different places and reorganize the interior. Conveying the message that it's not a safe nest.

Also full spectrum lighting  - 2 florescent bulbs CRI over 92 and output 5500. OR full sunlight not filtered out by a window. At least 15-20 minutes at least three times a week. If it's too cold where you live then go with the florescent bulbs.

Calcium you need to discuss with your vet. She is depleted when the eggs draw the calcium from her bones. Get Calciboost and give at least twice a week. Breeding hens get it 5 times a week. Ask your vet he may say more than twice because of her situation.

It is a serious issue so it's good you recognized it and you can stop it but it may take time. Tiels are difficult cases with this but try ALL the things we said. Occasionally the vet gives hormone shots but I wouldnt do that if I didnt have to. One poster even had a hysterectomy. Dont know if she ever tried these successful techniques though.

You're welcome. I forgot to explain about lengthening the nights/shortening the days. Birds have a sensor in the brain that regulates the metabolic process based on light. Like when they wake up in the morning which is naturally at about 6, they will eat within 30 minutes without fail (if the room is light etc.

So you want to simulate dusk and dawn. In other words you don't have them staying awake all evening then at some arbitrary time just turn off the lights.

My birds go to sleep by 7 pm no later. My parrotlets INSIST on going to their roost (a swing in the corner of the cage) at 6:45 sharp like clockwork. They REALLY need the 12 hours sleep like most parrotlets. Without it they are cranky, nippy and lethargic or hyper not steady and cheerful.

Anyway I give a dusk time. Around 6:15 the room doesnt have artificial light and I close the miniblinds about half shut. Then 6:30 I close them then wheel their cage into the bedroom. The blinds are only a quarter open in there to allow in some moonlight. Even if I didnt do that they still climb right up at 6:45 even in summer light. By 6:30- 6:45 they are in the roost grinding their beaks (bedtime prep for parrots).

It doesnt have to be a complicated thing, just dusk and dawn essentially. And a dark nights long quiet actual sleep.

So try to give a dusk time to her as a brain signal. Just like in nature only earlier in her case. REalizing you may work and have challenges. But give "dusk" for at least 15 minutes before she goes wherever she goes to sleep.

You dont need a cover in fact that's a fake thing humans invented so they can keep lights on while birds have to sleep. But it's rarely a good replacement and it makes the environment so structured if you are ever out you bird will probably sit there waiting for the cover. So I never do that. Anyway I think it's not good to have them sleeping in that stale air with dander and dust and stuff breathing it in all night.

You want her sleeping in a private semi dark area without tvs, music, computers lights flashing and human noise. Outside in the woods noise is different than human noise and birds sleep in a group and feel "safer" even if they sleep half alert for predators in nature. Hopefully you have a bedroom that you can use but if not do your best and if all else fails or you live in a studio or something, then you'll have to use the cover in a dark corner and it has to be the dark heavy bird kind not a thin sheet.

Then in the morning the same thing. 12 hours after she goes to sleep or at least 11 or 10 minimally if you have no choice,,,open the blinds a bit for 15 minutes then more. Then after that, regular light. She'll go eat and start her day.

The Calciboost can be ordered online if your vet doesnt carry it. It's really the best. If your bird is a strictly eating pellet bird (which I doubt) then you will not supplement with calcium or vitamins unless your vet says to. Man made supplements are bad with pellet eating birds causes vitamin toxicity.

Finally, I"d make the extra effort to give more enrichment to get her mind and hormones out of the egg laying cycle. Regular baths not with warm water, new toys, extra fly time (or no clipping anymore if you clip which I dont approve of and is not approved of by this club). More time out of the cage but not allowing her to find hiding spots even some birds go straight for the kickplate under the kitchen cabinets since it's like a dark nest.

Also don't pet her feet, beak or tail or back. Decrease this physical contact since it is like mating ritual. Stimulates the hormones, too.

Sal and Sally, I don't know what it is that you are asking exactly but, for one thing, I can tell you that your female will not last much longer if she keeps on laying eggs all the time.  You need to put them on a strict natural daylight schedule because it's the long artificial days (lights on when it's dark outside) that is causing their metabolisms to get all screwed up (birds only lay during breeding season, not all year round).  You'll also need to put them on avian liquid calcium if they are not getting any right now.

hi my name is eddie and i have two cockatiels and want know how you can tell male and female. pls help and thank you.

I have a pair of Cocatiels, they have been mating for about 2 weeks maybe longer, they dont seem to mind an audience, but I am concerned because she has not layed any eggs is that normal? I have a cardboard nesting box inside the cage( they would not go into the wooden on) and I have been keeping an eye on her, but I dont see any thing different or not right, can they be mating with no results........ Will that hurt them? HELP IN VERMONT

okay, i called an avian vet and they told me to place the nest box in there. I guess maybe i was mistaken. I am going to take it out when should it be placed in there? I am so confused now I have been doing so much research and everyone has something different to say........I dont want to have anything to happen to my babe's they are very important to me. But i am not sure i understand this whole thing, they can mate with out laying eggs..... is that right?
