Domestic chickens lay eggs, if I understand correctly, every day, fertilized or not. Is this true of bird generally? Or is that something particular just to domestic chickens? Or is it something some birds do however not others?


Well, nothing know about all birds, but I have the right to confirm the parrots can and also do lay infertile eggs. Well, at least the female persons do.

You are watching: Do wild birds lay unfertilized eggs


Not every hens place every day. They have the right to suddenly fairly for a while, and also start again there is no notice. Counts on the season, the feed, weather. Quite undependable creatures about here.

I deserve to tell you there is nothing more depressing 보다 buying chicken feed and eggs during the same trip to town.

Its mine wife’s gig.


Damn chickens. The hens we had actually were prolific, pretty much an egg a day per bird for number of years. Constantly amazed me. Those girls kept up a good appetite and went v a fair amount the crushed oyster shells on the side.

You would certainly think it would certainly be a an extremely inefficient process to it is in favoured by natural selection. Ns am surprised parrots perform it also.


My brother’s pets cockatiel lays eggs, though only seasonally (in spring/summer).

And my hens lay every day, as long as I remove the eggs and don’t let them accumulate. If 8 or for this reason eggs pile up, she’ll protect against laying and sit top top them. I understand that hens in climates that get cold avoid laying in the winters. Ns think it has to do with temperature or hrs of daylight or perhaps both.

And FluffyBob, i don’t think that an inefficient process at all. In the wild, there is a masculine in the picture, so the hens space laying fertilized egg that come to be the next generation.

Hours that daylight. Bright irradiate (sunlight or a 60 watt light bulb) is required for stimulating the pineal gland, between their birdy small eyes. Prior to electricity, eggs to be a spring equinox start treat, which may be why they space a component of so numerous cultures’ springtime holidays.

It evidently settled very well for the species: chickens are extremely successful.

It’s the same for navel oranges: both emerged a properties that seems on very first glance to be counterproductive, yet which, due to interaction v humans, worked out by well.


All birds can put infertile eggs, despite in most species they don’t execute it very often, at least in the wild. Normally, there’s a collection of ecological triggers (which can include stuff like nest building and pairing, as well as day length and temperature) that stimulate the release of egg in wild birds, yet this can misfire sometimes, or fertilisation can be unsuccessful, despite mating.

Pet bird of several varieties are well-known to lay also when maintained singly, others will certainly sometimes type a pair with an additional female, fulfilling the ecological triggers needed, and also both will lay in a shared colony (and they keep sitting because that ages, the both funny and depressing come watch). No other types lays as countless eggs as residential chickens though- the is, ~ all, what they to be selected for- also the wild ancestors of chickens, jungle fowl, i will not ~ lay more than around 20 eggs a year tops, during the breeding season, and also normally will just lay about 6 eggs- one typical sized clutch- in the year.

Other domesticated varieties kept because that eggs, such together quail, and some ducks, can additionally produce pretty superior numbers that infertile eggs, yet chickens have a much longer background of selection, and are quiet the many productive.


Anecdotally: Turtles likewise lay unfertilized eggs. Ours pet box turtles got together and produced some baby turtles. The masculine was ultimately packed turn off to live in spoiled bachelorhood with household friends, but the female continues to lay egg every year.

I an extremely much doubt natural selection had lot to do with the ;). Domesticated species have been rather thoroughly re-engineered by guy on just around every level.
