A bilby does not lay its joeys: it gives birth to live young. It tends to have one to three young at a time, averaging two.
Bilbies generally have two joeys at a time. A female bilby may have one to three babies in a litter.
There is only one species of bilby remaining. It is the Greater bilby ((Macrotis lagotis). There was one other species of bilby, now extinct, and that was the Lesser bilby (Macrotis leucura).
There is only one species of bilby left. It is the greater bilby (Macrotis lagotis)so it is therefore the most endangered bilby.The lesser bilby (Macotis leucura) is believed to be extinct.
The Greater bilby, with the scientific name of Macrotis lagotis, is a small marsupial of Australia. It is a member of the bandicoot family, and a nocturnal omnivore which is found in arid and remote areas of the continent. The Greater bilby is the only surviving bilby: its cousin, the Lesser bilby, has not been sighted since 1931.
they can lay 1eggs in one time
Koalas usually have just one joey, once a year. Twins are very rare. Female koalas are able to breed from the time they are about two to three years old, and they may produce a total of five to six joeys during their lifetime.
The bilby has become Australia's new symbol of Easter. In Australia, the development of the Easter Bilby has been a protracted campaign by many groups concerned with preserving the critically endangered bilby. The idea of an Easter bilby has actually been around since the 1970s. One of its sources may be a book entitled Billy the Aussie Easter Bilby being launched by author Rose-Marie Dusting, in Adelaide in 1979. Dusting donated a percentage of the sales of her book to conservation of the bilby. there are other claims of small groups implementing the concept of an Easter bilby, all around the same time, i.e. late 1970s to early 1980s.

they lay many eggs because most of them are eaten before they hatch
If they are happy they should lay just one a day but I have had a duck lay 2 or 3 in one night a few times
On average, mammals give birth to between one and four young at a time, depending on the species. Animals such as dogs and cats easily have up to eight (or even more) young. An unusual mammal is the Tasmanian devil, which gives birth to between 20 and 40 joeys, although only four can actually survive.
