assistant
The main difference between a hen and a rooster is their physical characteristics. Hens tend to be smaller and leaner than roosters, with curved combs and wattles of different shapes. Hens usually have feathers of a single color, whereas roosters usually have feathers in multiple colors. Furthermore, roosters are known for their loud crow, which can be heard all throughout the day, while hens lay eggs.
