Single Parrots and Egg Laying

I had a call on my answering machine when I got home today:  “Hey, ummm, STANLEY just laid an egg. (laughter) One of us is really confused.”  That really made me laugh.  I clearly remember the day that my Henry laid a clutch of two.  Sometimes this is how we find the true gender of our parrots.  It’s that time of year.  The bird talk boards have egg laying posts all over them.  Someone I know just had to have what she called “the mother of all eggs” surgically removed from her cockatoo.  It was HUGE!

The question that most commonly comes up is: how can a “single” parrot produce an egg? Egg production is not the consequence of mating. A female parrot will produce an egg because her body reacts to certain stimulus that tells her it is time to do so.  In the wild, things like change of season, increased daylight hours and more availability to certain foods signal the breeding season. 

In our homes, our parrots react to the same stimuli. The way that we physically handle them and even a bath (reminiscent of spring rainfall) can bring on the hormones which can result in egg laying.  These eggs will not be viable, as there was no fertilization by a male, and will not produce babies.

So your parrot has laid an egg, now what do you do?

If yours is a single female parrot, and there is no chance that this is a viable egg, let her keep it (or them) for a few days.  She may choose to incubate and turn it, like a doting mom, and might lose her interest after a while, and if she doesn’t, take it away from her in her absence.  Removing the egg immediately will only serve to cause her to lay more to replace it instinctually, which can lead to health problems.  Some choose to remove the eggs right away and replace them with similar sized pebbles or plastic eggs.  Strangely, they often don’t seem to notice and continue to incubate them.

The shell of an egg is made primarily of calcium that comes directly from calcium stores in the female’s body.  Their bones and muscles provide almost all of the calcium needed to produce the shell.  Excessive or chronic egg laying can profoundly deplete the body’s calcium (hypocalcemia) causing improper body function.  Hypocalcemia can lead to egg binding, where the uterine muscles do not expel the egg .  It can also cause seizures and brittle, easily fractured bones.

Egg binding can be the result of a number of things including obesity, large or poorly formed eggs, bad diet, even bad genes, and it requires immediate vet attention. This is not uncommon with cockatiels, lovebirds and budgies.  Signs of egg binding might be lethargy, sitting at the bottom of the cage, large or excessive droppings or none at all, straining, standing/perching with the legs further apart than is normal or a swollen vent area.  Often the vet can “coax” the bird along with the aid of warmth, a lubricant, and  the injection of fluids, calcium, antibiotic and steroids. 

Sometimes the egg can be palpated out (only by your vet), being very careful not to break the shell.  Sometimes, depending on the location of the egg,  a needle is used to extract the contents of the egg, and the shell is crushed so it can be passed.  If the egg breaks, or breaks down inside the abdomen, it can lead to a serious inflammation called egg  yolk peritonitis, which is life threatening.  These are all very good reasons NOT to let your parrot overproduce eggs.

If your parrot is laying eggs, excessively or otherwise, there are environmental changes you can make to deter her.  Keep her away from  dark enclosed areas that can be perceived as nesting spots.  Limit her daylight hours to 8 – 10 per day.  Avoid warm, mushy foods like mashes.  Bathe her less frequently. 

Be careful to touch her around the head and neck only, and if she has a favorite toy that she is behaving sexually with, remove it.  Be mindful of her diet.  If she is laying excessively, and until you get it under control, she needs nutrients to handle the task.  An all seed diet will not provide her with the calcium she will be needing.  If these methods don’t work your vet might choose to administer hormones.

A bird laying an egg is the most natural thing in the world, and as long as your bird is healthy, it isn’t a cause for concern.  It’s just one more of the many incredible things they do.

My african grey has been not talking as much last week. will to my surprise there was an egg in her cage the other morning. it has been 3 days since she laid the egg. she is no talking as much, is this normal? i am not breeding. her egg was not fertilized.


Hello, I have a pair of cockatiels that “mate” but never fertilize the eggs (to my relief). The thing is that the female is laying an abnormal amount of eggs this year, 10 so far, and I am concerned about her calcium levels. They eat all natural parrot pellets, but should I put an extra source of calcium? And if so, which one?


I had experence with my conoure,she is in her 2yr of egg laying. The vet told me that,I should leave the egg in for a short period. If you don’t she’ll never leave her nest to eat,as long as she’s sitting on her egg. I was told on line,by experts,when I first got her that the egg laying wouldn’t start,until she’s 5yrs,she is 3. I give her calcium in her water,while she’s laying.


Hi Vi, Yeah, the experts…my experience is that there are none really. Science is always learning new and surprising things about parrots, and we are as owners as well. From the info you’ve given, your conure started producing eggs at around one. It is early, but certainly not unheard of. Jamieleigh has a larger parrot that is showing VERY early signs of sexual maturity. It happens. I agree with your vet that you should leave the eggs in the nest for a little while, but only because you don’t want her clutching again for health reasons. With regards to the bird not leaving the nest to eat while she’s on an egg, don’t worry about it. Think of it this way: humans are the only species that mate for pleasure, the rest of the animal kingdom does it instinctually for the continuance of the species. A mother bird also knows instinctually how long she can leave the eggs before it will cool down to a critical level. She also knows that if she is dead from starvation the chicks will not survive. She will find a way to sustain herself for the lives of the chicks. You may not see it, but she’s eating. Patty
