They can, but the egg will obviously not have an embryo inside. This laying causes an incredible amount of stress to the bird, so she must receive calcium supplements. If the egg is removed from the nest/cage, she will likely lay another one, so some pet stores or bird specialty stores carry fake eggs to put in, that won't rot like real eggs, and that will lower the likelihood of her laying more.
Yes, they can, and it is sometimes a very common occurrence with females who are in season and have a strong desire to nest. They don't even build a nest;they ju lay them on the cage floor! When this happens it's best to let her sit on the eggs for a week or so and then remove them. If you remove them earlier she'll be prompted by instinct to lay more. The n your remove it again, and she lays more eggs and so on and so on. And tehn she'll have a vitamin C deficiency and that means trouble.
It's perfectly normal for parakeets to lay eggs without mating, the eggs are just infertile. Like hens lay eggs without roosters.
A female parakeet can lay an egg without a male, but it will not be fertilized, therefore the egg will not hatch. So, yes, a female parakeet does need a male to "hatch" an egg.
Yes, although I've heard that they lay empty eggs when there's no mate. But they have to be a certain age. :S Hope i helped
Yes. Even if they do not mate the female will lay an egg regardless of proper nesting enclosures being present. Though if healthy hatchlings are intended, a nesting box should be installed.
It maybe felt territorial and felt a need to protect itself.
yes...
No you need to have a female and male duck to have baby ducks.
You can do that to make the exact same Pokemon but you can use a male and a female of different Pokemon too. If you do that instead who knows what will hatch out of the egg...
yes you do because if you only have a female toad itll only have eggs and they don't hatch and if you have m. an f. together the male firtilisers the eggs this may sound discusting but it furtilisis it by peeing on them
to have a chick yes you need a male and a female but if you want the eggs you have for breakfast no you don't need a male
No, You need a male holly to get berries on a female plant.
You will need a male and female version of the pokemon you want, then put them both in the day care at the same time, for example, a male and female pikachu will give you a baby pichu when the egg hatches. to hatch the egg you will just have to walk with it.
The same as all other bird eggs - 37.5C, give or take a quarter degree or so.
No. In parakeets the color of the feathers is not how to tell the sex of a bird. The area where the birds nostrils are is how you tell the sex of a parakeet. If this area is a greenish or blueish it is a male. If this area is a light tan or pinkish it is a female.
no you need a turtle.....a BIG turtle
Well first you need a female Abra and then you need a male Hitmonchan, Electabuzz/Electivire, Medicham or Magmortar that knows Thunderpunch then you just breed them, a Pokémon Egg will come out that will hatch into an Abra that knows Thunderpunch.
