I have fifteen pullets (knock wood) and a bonus roo hatched 7/5. Just started letting them out into a small run last week -- later they will free range. The run is small by necessity (otherwise it would jut out into a traffic area in front of my barn). I may also start tossing a few of them into my seldom-used dog run, so I don't have to weed whack it. They are eating tons of grass and weeds in the run, and I'm throwing stuff in as I weed, trying to see what they will go for. (So far: tomatoes, sorrel, clover are a big YES, lambs quarters, burdock, quack grass, and wheat, of all things, notsomuch.) They also get a big serving of Japanese beetles when I empty the traps every day, so lots of protein in that. A little bit of scratch as a treat and inducement to go in to bed at night. I've been reading about restricting chickens' access to their feeders in order to encourage foraging and cut the feed bill. There will be epic quantities of forage available to them here (we are on a remote 26 acres of pasture, hayfield, scrub and woodland). At what age would it be reasonable to start closing away their feeder for part of the day? For how long? I don't want to stunt their growth or delay laying, but I'm all about being cheap and getting the girls to pick up the tab for their own lunches. I'm already quite sure that their feed consumption is much less than it would be otherwise.
