I have a couple of pekins and a partridge wyandott, and they lay quite well. The yolks of the eggs are bright yellow, and are great in baking.
You don't need to clip their wings; it is pointless, and they'll still find a way to escape if that's what they want to do. They are very clever creatures.
Ours have a small run that they sleep and lay in. It has a door that we leave open during the day, and they rome free around the property all day. We live in the middle of town, next to a very busy street, and the chooks never run out onto the road. We feed them plenty of scraps. They like worms and bugs too, which they get from the garden. They also need a bit of grit if you aren't going to let them out of their run. Ours don't need it because we have sand and fine stones lying around the house, which they peck at. You can also get them calcium and mineral cakes, but that isn't completely neccecery. Plenty of clean water is a must. We give them fresh meadow hay in their run. Wood shavings are messy, and they aren't very soft for the chooks either. The chooks come inside sometimes and steal catfood, and even pieces of meat that my mum puts on a plate for the cats when she's making dinner!
