I have been letting my 4 grown BO girls, and my 2, 19 week old Delawares "free range" most of the day. They LOVE being out. We have approx 20 acres and they have a lot of room. Anyway, we have noticed that when they free range, they eat much less layer ration. We still get 2-3 eggs a day although getting eggs is just a bonus for us. We are not raising them just for eggs. My question is "do they get enough nutrition eating whatever they eat while they're out"? From the looks of things, they LOVE my flowerbeds. I just don't what them under nurished simply because they like to roam the place. Any advise?
