In late August I had to stop free ranging my flock due to predators, lost half my flock over the summer. And since then the egg production has dwindled to maybe one egg a day if we are lucky. I have 1 barred rock, 1 black austerlop, 1 brown leghorn, 1 white leghorn and 3 Rhode Island reds; I do have 3 roosters. Their run is 20'x25', which I feel is big enough. Feed is the same. Can offer any advice.
