I've "heard" that it's the grasses etc that make the free range chicken eggs that nice dark golden yolk color.. we feed ours scraps from the kitchen & hang a cabbage now & then... but due to neighbor dogs, we haven't let ours free range the back acre that we have... I would love too, but not being home, I'm fearful of losing some to dogs. What can we feed them, that they will love..and that will help enrichen the eggs.. like we see from those that are able to let theirs roam freely? I saw a bale of alfalfa the other day at a feeder store.. would they like that? I gave them some grass clippings the other day after cutting the yard.. they really at that up fast... Thanks for any and all input.
