No. You don't need a rooster for your chickens to lay eggs unless you want fertilized eggs. Does a woman need a man to expel her eggs? No. Same thing. You only need a guy if you want kids.
No you don't need a rooster for a chicken to lay eggs.

No, but you need a roster to protect your hens from wildlife. No hens, no eggs!

No. But if you want to have baby chicks, yes.
