No, Rayquaza and other legendary Pokémon cannot lay eggs.
first you need to have a male and female Pokemon or a ditto then you check on the man out side and if he says there getting along that means there is going to be a egg.
ny pokemon with a gender can lay eggs. If the pokemon can only have one gender then you must breed that pokemon with a ditto or another pokemon in it's egg group (This has been called a glitch before in pokemon diamond and pearl). The egg groups basicly mean any pokemon in the same egg group can breed together to make a baby pokemon. The female pokemon will be the one who the egg becomes of course at it's most basic stage of evolution.
To get your pokemon to lay an egg you have to put 2 pokemon in the daycare.It has a better chance of laying an egg if you put Ditto in the daycare with the pokemon.
Mew can't lay an egg.
in this case you need a ditto ditto will lay an egg with almost anyone. but a male can not lay an egg.
the quickest and easiest way to do it is to get Pokemon emerald and catch a ditto and migrate it to platinum then put it in the day care with the starter Pokemon and wait till they have an eggPS: it will never be dittohope this helps
