Since Hurricane Irene we've had to keep our entire flock in two smaller pens (aka FEMA trailers..lol) while we rebuild our big pen. Because of that we have been free ranging them more than normal. We used to free range 4-6 hours a day, but for the last couple months they have been free ranging 12 hour days at least 4 days a week. Even though we have feed out for them 24/7, I am noticing that they hardly even touch it if they are free ranging. They have several acres to scratch and forage on so the feed just gets ignored. I'm happy that we have a lower feed bill of course, but I just want to make sure they are getting what they need. Everyone is acting fine, laying normally (aside from the fact we have 2 in molt right now) and seeming happy. Should I assume that if they need the feed, they will go get it? Or is free ranging enough? I should also mention that we raise all layers, no meat birds.
