I posted a thread about making something like this yesterday and I was also asking questions about what to plant. I didn't know there was a similar thread already started but I'm glad I found it. I think I'm gonna use some hydro wheat and see if the chickens like it. You can always count on BYC members to come up with something to make the chickens live a better life, Thanks mother_hen6
