I have 5 hens, i get the flock block and drill a hole in it and hang it from the rafters with a rope. I hang it just about chicken head hight. My block last for 6-8 weeks.
I feed blue seal layer pellets freely in a hanging feeder, mixed with a little oyster shell, i toss scratch grain in the run when i visit the chickens, they free range about two hours every evening, and they get all of our table scrapes, left overs, trimings and pealings and garden spoil. They are heavy and thick and densly feathered. I get 4 eggs a day from my flock of 5.
