Chicken poo a lot. But compared to a horse, a horse is more work in maintenance upkeep!
If you can keep a horse, you be fine with a small flock of chicken.
If you live next to a busy road, I do NOT recommend to free range the chickens. Keep them enclosed.
And Silkies are wonderful breeds. But they are poor egg layers. Very docile toward bigger chickens. Get two Silkies and the rest be something that meet your other criteria of maybe being good egg layer breeds.
