Bee, thank you so much for directing me to this thread.
I have been doing as much research and reading as I can on good ways to make me and my flock more self sufficient. Not only will it be cost saving once established, but I believe it will also be much healthier for my chooks as well as for all of us that eat their eggs and meat.
I have been looking into which native grasses are the best nutrition for them. However, the only source I found to buy seed for the grasses native to my area are frighteningly expensive. So I am thinking that I may try to gather some seeds myself and/or dig some up to try transplanting. For chicken "lawn" areas I'd like to encourage a mix of native grasses interspersed with alfalfa, clover and such. I don't know how the alfalfa and clover will do in my heat and drought heavy area without lots of extra watering, but I want to find out.
