I recommend the novel Super Doomsday Chicken Farm. The novel was set in the post-apocalyptic world. The protagonist was the owner of a chicken farm. He raised many different types of chickens, and each chicken had its own special ability. One of the roosters was called Liu Xidan. Like the other roosters, he wanted to escape. This novel might meet your requirements for the protagonist to be a rooster.
The two books," The Crazy Wife at the Farm Gate " and " The Crazy Wife at the Farm Gate 2: The Husband Can't Keep the Starting Point Too High ", both had plots where the female protagonist called the rooster husband and the rooster bowed to the court.
You can start by sketching an oval for the head and a larger oval for the body. Then add details like the eyes, beak, and comb. Don't forget the legs and tail!
