Child of Noah- I fill up the FF feed trough every couple days or when I remember. It's never gone bad even when the temps were recently in the 80s. It dries out some but the girls seem to think it tastes better when I scrape it onto the ground 
RR- I have 4 hatchery girls that were on layer pellets at 10 weeks when I got them. I continued that until I learned about FF. 2 of them had prolapse. I stated adding manna conditioning feed to their FF (layer pellets, scratch, BOSS & layer pellets) About a month or two after adding the conditioning feed their prolapse is GONE. It's the only change I made in their FF. I also add various herbs & garlic to it as well. They filled out wonderfully. For the warmer months I feed at night. I use a small dry wall pan. Fill it about a 3rd full. It usually last 2 or 3 days. While I don't free range because I live in town they are let out in 300ft of electric netting. They are at the door waiting to go out & look for food. Lots of dirt and bugs. Rarely do I see them at the FF trough. that tells the newbie in me that they are getting plenty to eat in their fenced area. They love when I mow the grass. Brings the bugs out. I also keep some pieces fire wood on the ground to move around so they can get bugs under them. Oh and I also give en eggs and animal protein several times a week. They change in them since I added the conditioner was great. And more animal protein seemed to help as well. But yes they do run to the coop when I get close. More habit than anything I think since they just peck a little at the food then back outside.
LM- thanks for the Great info again. I do read it all.
