Fodder/fermenting for chickens

I have four lazy 3 year olds and 8, 16 week old chicks. With the sudden surge of feed needs, I have started growing fodder for my chickens. I use a mix of barley and winter wheat seed. I also throw in a few flax seeds and some chia. The young ones tear it apart quickly. The older hens dont pay it any mind. I am trying to decide if it would be worth while to add in some herb seeds. I have read that many herbs have great health advantages for chickens. For example I have read that oregano is great for the immune system. My question is, if these plants really do help, is it worth it to add a few seeds into the fodder seed? It won't cost much up front so I dont see harm in adding them anyway. I'm just curious whether i would be wasting my time.

I am so glad you posted this, because it never occurred to me to add herbs to my chickens diet, but I will now.  I ferment barley, and wheat for my chickens.  I was growing it into fodder also, but lately I have been letting them out a few hours everyday, and I thought they probably get enough greens eating grass, weeds ect.  I can't find anything on putting herbs into fodder, but there is lots of great info on feeding chickens herbs, and using them in and around the coop.  If it's as good for them as what I have read then I can't see any harm in throwing them in your fodder.  If you have space your might be better off growing the herbs, at least the perennial ones, and just removing bits of the plant, it would be cheaper then buying seeds all the time.  It will be interesting to see what others have to say.  Maybe someone will know the science of nutrition and health benefit of mature plant compared to herb sprout.  I enjoyed a couple of sites I found on the net, if I can I will make a link.  Good luck, and Thanks.
