I've revamped the way I do things, but last summer we bought three pullets and two roos at the local auction. My neighbor said they were red sex links. After keeping them in a cage for a couple days, I let them out with no facilities whatsoever. They stuck around. One of the hens got lost eventually, before they started laying, and I sold one of the roos. I also added a black hen of unknown variety with feathered legs. These chickens were completely free range and I did not feed them ANYTHING. When the two remaining RSL pullets started laying, and I found out where, they did not miss a single day for three months. That was with no supplemental feed. The black hen did about 5 per week. Then a neighbor three houses down complained to the sheriff that my chickens were free-ranging in her yard, and so I had to catch them and take them to my friend's house to keep them for me. I got them back now and have them at my boss's house where they have plenty of room to free-range and he has other chickens there and they have access to grain. The day before I caught them one of them laid a huge double-yoker which we weighed and it was well over half the weight of the world record. Free-ranging can work, but they have to have enough free range for them to go on.
