Have 30 layers.
Some folks don't know this but you don't need a rooster to get eggs so if he gets to be too much of a pain, enjoy some chicken soup!
I use laying pellets or crumbles. I like the pellets better because I think there is less waste. Try to find a food company locally that sells all natural feed. It is much better for them and better tasting and better for us when they don't have all the antibiotics in the food like most places, D&B included, has.
Hens need a certain amount of light to lay so a light on in the hen house to get you 15+ hours will get you maximum laying. I usually run a light until summer then let them naturally slow down in the fall until they molt then I start with the light again and get them laying.
Fresh water, lots of ventilation and some natural food will get you going!
