Oviparous animals are known to lay eggs. Some egg laying species are internally fertilized while some are externally fertilized.
Birds lay eggs, they do not have a baby. A bird may lay eggs and sit on them but unless there is a male with her, they are not fertilized and will not hatch.
One without a mate? No, the egg needs to be fertilized or the egg would never hatch. Yes, female birds lay eggs on their own but they still need a mate to fertilize the eggs.
A mother bird will lay an egg when it has breed with a male bird.
The Dodo bird is extinct.
Only if they have mated with a rooster. Even if a rooster in in a flock though, her eggs may not be fertilized, as he may not have mated with her. In that case, if you really want the hen to lay fertilized eggs, you could consider penning the rooster and hen up together for a few days.Actually, you can eat the fertilized eggs. It really makes no difference.The answer to your question is that yes, hens lay fertilized eggs, but only if she has mated with a rooster. If she hasn't, the egg isn't fertilized.
