It is possible but unlikely. Emus become fully capable of reproducing between 2 and 3 years of age.
Yes. As with all birds a male is needed to fertilize the eggs.
When a female is in heat she will accept more than one male to breed with. If there are enough eggs, the sperm from more than one male can fertilize different eggs the female has.
A female will lay eggs wether she has a male to fertilize them or not. These eggs will never hatch without the male. But with a male and female they will have intercourse where the male will fertilize the female and then after a few months the female will lay fertile eggs and a few more months they will hatch into baby geckos
Females don't fertilize eggs it is the male that fertilizes the eggs
It is likely the eggs are "spermed" (for lack of a better term) after they are layed. **This happens in the wild as well. The female does not need a male to lay eggs, but the eggs need a male to fertilize the eggs. The eggs will just stay eggs in the tank without a male to fertilize them. The female may also eat the eggs if left in there with her.
The answer is yes. Fish do need at least one male in the tank to fertilies the eggs. However in some cases the fish will first lay the eggs then the male will fertilize them.
No, they fertilize it before they are layed
Females don't fertilize eggs it is the male that fertilizes the eggs
As soon as the male serves the hens then the eggs should be fertilised.
to fertilize the eggs
Sometimes
You will need a female to lay the eggs and a male to (first) fertilize the eggs.
